I have a WordPress site hosted in a server. I also verified the server configs everything is perfect. No space or ram issues.
When I start to load my site URL. In my networks tab, I see that the first request was "instant-loan/" which took 1min and rest all requests come faster after that. Ofcourse they loaded from cache in the image I shared but if I open in incognito also the rest of the requests are in miliseconds. This happens in all pages,
What could be the issue here? I have been searching for a possible cause for a very long time.
I have performed a site performance test in google insights and GT. They both gave the same below results:
Page loading: 35sec.
They only say to optimize images and js content.
The total page size is 6mb.
214 requests are beeing processed.
[NEW EDIT]
Below is the performance result. It shows a lot of idle time and js image rendering seems to happen quite fast. A max of 4 sec to render, load the site. Thus I assume there is something wrong with the server. I have minified CSS and JS. Also, use compressed images only. Is this because of any mysql connection issue ?? Has anyone faced it?

Here is my page URL: www.1800-gifts.com/USA/Cake-Delivery and other pages like that all are loading very slow even i have caching , compression enabled, i have tried to call go daddy which is my hosting provider but they do not respond positive.
Developer is telling me that it is a server issue, but i don't find any issues in server it is fine.
This website is developed in asp.net 4.0, database is mssql 2012 r2.
server is VPS, with 2 gb of ram, I have 2 GB data in database, and some table contains more than 100k records.
Please look at my site and give me suggestions, i have checked in google page speed and other tools they are all saying different views.
I am not sure if this is the cause but if you enable developer mode (F12) and run the site in chrome you will see that the cake-delivery page is the one that is causing the loading time (44s). You will also notice that there are JQuery errors on the page.
This could possibly be part of the problem.
EDIT:
After looking at the linked page I think Erik is right, JQuery is not the issue.
The person that is developing the site needs to revisit the way the page works completely. There is a massive amount of operations happening in the page load of the page. The operations that are used are also hack and slash ways of doing things that there is already built in methods for. This is simply a page taking forever to load due to bad coding.
I would suggest the developer returns to the drawing board.
There are a lot of great tools that look at your page and tell you what might be wrong with it. Analyzing your page with GTmetrix for example gives you this. There are also important tips you can work on right away, for example:
gzip compression
Minifying css, html and js
Concatenating scripts
and a lot more. I also recently wrote an article showing important optimization for web performance
Looking at the waterfall chart of your page (also available on GTmetrix) shows that the biggest problem is indeed your server. It takes 16 seconds to receive an answer for the first request (time-to-first-byte). There is clearly something wrong!
There are a lot of things that could be wrong on your server. You should test your database queries (are they slow? How many are performed for a page load?).
I use mod_pagespeed on my Nginx-Webserver.
When I try to test some of my pages with Google Pagespeed Insights(https://developers.google.com/speed/pagespeed/insights) there are:
1) Many errors shown the first time I do this, when the page is not opened manually with a browser before.
2) At the second scan - or if I open my page manually with a browser before - Google Pagespeed Insights shows me 90+% instantly.
Some of my sites do not have very large traffic, cause they are niche specific. I do this speed-optimation mostly for ranking purpuses. Now I am worried that Google doesn't see the 90+% when they test my site, because the first scan shows 70-80% and many errors...
Ok... so I think mod_pagespeed purges its internal cache after a while and when the first one opens the site there are no optimized files and because optimation takes to much time, the first user gets some files without full optimation. Right?
My approach nr.1:
I have done some optimation so keep the cache for 12h, but my tests show me that it doesn't work. Are here any mistakes in my attempt?
#experimental mweber 400mb 12h
pagespeed FileCacheSizeKb 409600;
pagespeed FileCacheCleanIntervalMs 43200000;
pagespeed FileCacheInodeLimit 500000;
My approach nr.2:
My hoster give me the advice to warm up the cache with a wget-script, which opens my pages from time to time. I tried that but it doesn't show any effect, so are there any requirements or parameters I have to use with wget, so mod_pagespeeed starts optimation of files?
Would be great to get some tipps and advices from you! ty :)
wget will not trigger any caching, if caching was only triggered via request then wget would not access the files to trigger them anyway as it does not process html to trigger requests on the assets.
Why are you clearing the cache so soon?
I've a Ajax .net website which follows this structure :
Control (ascx) : TopMenu, LeftPanel, RightPanel, Footer, all are very simple controls and don't require any connection to database or server side code !
One div body (ajax)
Everytime the website starts, the 4 controls load first, then comes the Ajax body. The performance is pretty good in development environment.
But when i uploaded the precompiled site to the host, it always take quiet long for starting up, after the first load, the performance is good
What i can't understand is : as far as i know, the four ascx control will be rendered first, that means the page will be loaded to the client, after that is the ajax content. So what's causing the performance on start up ?
P/s :
i did set the key compilation=false in web.config
i compiled the site using Publish tool in VS 2010 (Release mode and not allow updatatable ... )
i have no images on the site, it's a very simple site
i've checked similar topics, and event posted a question not so long ago about
this, but still without success

From your site and running the Network Analysis on google chrome what is blocking the render of your site is a huge delay for make a lot of calculations on page load, there is a lot of time that takes to start get data.
Also the google analytic script, must be placed on bottom of your page, together with other external scripts for google plus, facebook like etc.
Also there are 2 fonts on this css, that can not be load, and this takes almost 3 seconds delay.

If you are referring to the very first request after deployment to production. I don't think there's anything you can do about it. ASP.NET first request will always be slow, even if it is a pre-compiled site because the server still needs to load resources on the server-side.
But, if you are talking about first load from the client-side perspective, by just running Chrome Developer Tools I can see that your site's home page is quite heavy (44 requests, ~4 seconds to load) which explains why the first load takes some time and sub-sequent requests are quicker...mainly, because most of those 44 requests get cached by the browser. Now, in your dev environment it happens quickly because there is no significant network latency or connection hops, once you move to production the network lantency and connection hops plays a big role in performance...that's why many sites use CDNs.
Suggestions
Make your site lighter. There's many things you can avoid. For example:
This background image (http://iketqua.net/img/header_bg.png) is useless because it is a plain color which you can easily achieve that using css. That'll translate to one request less
Bundling and minification tools to minify and merge style sheets and js files
Optimize your css. Take the time to review your css and clean it. I can't believe that such a simple page can be requesting 9 css files...probably most of them are coming from open source frameworks (jQuery UI, DatePick, etc)
I lack permissions to post this as a comment, but if it's fine in the development environment, it may be something as simple as ability of the host or the connection to the host.
After the first load, the performance is good
I'd be inclined to think this is due to the site being cached.
We're using the Telerik.RadScriptManager to dynamicly register resources depending on the controls on the page. These get combined and served as a single .axd for all .js files. This works fine as long there is no "heavy" load on the page. Under load the inital loading of the Telerik.Web.UI.WebResource.axd takes up to 10s, reloading the page afterwards however is instant (~10ms). The file is around 200kb in size and in FireBug i see the browser "waiting" for the request. This happens per user/browser, it isn't cached globally on the server. The server CPUs aren't stressed at all (<10%), so where is the bottleneck? What takes so long? Any hints where i could investigate this further?
Thx
UPDATE:
Narrowed it down to the RadScriptManager EnableScriptCombine feature. Disabling this and there is no performance impact anymore. But then I have 20 more requests...
Anyone an idea how to speed this up? Another idea would be to generate/combine the script with the RadScriptManager and then saving it next to the page as it won't change.
I'm on VPS hosting with dreamhost and am experiencing very high page load times. Here is the output from Devel module for mysql queries.
Executed 190 queries in 227.67 milliseconds. Page execution time was 21969.43 ms.
Using the module profiling at http://2bits.com/articles/measuring-memory-consumption-by-drupal-bootstrap-and-modules.html it seems ok:
total: 304.15
So if the modules are taking 304ms and the mysql is taking 227ms, where could the other 21 seconds be going?!
Here is the url http://5oup.net
As always any help very much appreciated!

You are not compressing your JavaScript of CCS files, it shouldn't be the cause to such a slow page load. It seems that you have your site setup for development mode, which is quite ineffective for a production site.
I tried browsing around, and I didn't find any page that was as slow as you describe. But the point above is a major point for performance improvement.
Some ad hoc testing on the home page gives me about 8-12 seconds per request (forced reload to exclude local caching). According to firebug, the biggest waits are due to loading all the images for the rotation, closely followed by the separate and uncompressed css and js files.
With local caching, this goes down to 1-4 seconds, with most of the time being spent on waiting for the server to actually respond with a '304 - not modified' for all the files involved.
So your first goal should be reduction of the number of separate files:
For the js and css files, combining them into single files and turning on compression should already help quite a lot - check your site settings under admin/settings/performance.
For the rotation images, this would require more work, as you would either have to combine them into a sprite or add the logic to only load one with the page itself and pull the additional ones later on via js.
You should try the css/js combination first and see if you really need more tweaking after that.
I found the very high page load on the home page was down to simplexml_load_file(), which for some reason was not enabled on my host.
