Very Slow Wordpress Performance after moving to VPS? - wordpress

We are struggling with the speed on our wordpress website. Have just moved to a VPS and this hasn't helped the speed at all.
Can anyone offer any recommendations on what needs to be done?

You have some javascript errors, looks like not loading properly. How much ram your vps have, thats other issue might be. Avoid 404 on resources (images, css, js)

Provide more information on your setup.
Try install Google PageSpeed and test your site here

Running your site through Pingdom shows a 4 second time to first byte. This suggests you main issue is definitely server side. There's a couple of diagnosis plugins that you can install which will reveal which plugins may be slowing things down*, and which DB queries are expensive:
Query Monitor
Debug Bar
P3
Once you've worked out where the slow downs are coming from, you'll be in a better position to solve them. You might find you have one query in particular that is especially slow.
* I've always found WooCommerce to be on the sluggish side, but them's the breaks.

How to reduce ttfb time in wordpress sites?

How to reduce ttfb time ?
my wordpress site has very long ttfb time.
i tested result several time and result absolutely confuse me sometimes is lower than 200ms sometimes more than 5s !
what is the problem ?
network configuration or server side scripts ? or something else ?
It is not really a Wordpress specific problem as all websites should try to have a ttfb time as little as possible.
Generally speaking when you use a tool like Google page Speed or PingDom (to name a few), you should get some advices on how to improve your ttfb time.
Like using a cache system, compress and regroup JS/CSS files, reduce images size, using a CDN, etc...
Now on Wordpress ecosystem, you have a lot of plugins what can help you with that (especially if you're not a developper).
Here is a list of some I know and have already used that may help you:
W3 Total Cache (caching plugin) - A good free solution for setting a cache system on your WP (realivelly complicated to handle though)
WP Rocket (caching plugin) - an excellent non-free solution. Work pretty well (much easier to handle than W3 Total Cache). Affordable.
Imagify (image compression plugin) - this plugin re-compress and optimize you medias. It is developped by the same company as WP Rocket, you need to create an account on there service to use it. And they have a free plan.
In any case, if you're not a developper, I encourage you to get help from one because some caching options can produce unwanted effects like a JS component that doesn't work anymore of stuff like that so you need to test if your website still works each time you make a change.
Note: long ttfb time can also be related to the server itself (mutualized one for example).
Hope it help.

Multiple instances of WordPress index.php running?

I seem to be dealing with DoS attacks or something and I'm not sure how to resolve this.
My server will start running slow, and when I look at the current processes running I see something like this...
Each of those is chewing up 4% of the CPU, and they keep piling on, and the CPU usage actually keeps growing.
Sometimes they will all go away again and things will run smoothly again after a few moments, but other times it ends up killing the server response and I have to restart the service.
I'm on the latest version of WordPress with only a few plugins installed like Google Analytics, WordPress SEO, Gravity Forms, WooCommerce, etc. Nothing that should be giving me any problems. All plugins are up-to-date.
My hosting company isn't being much help trying to figure out why this is happening. They just keep saying it's a WP problem.
Any information on how I can resolve this would be greatly appreciated. Thanks!

Site is abnormally slow

My site is running on Wordpress and uses Woocommerce to display most of the content. See my site here, I have a lot of images that could be part of the problem...
Google PageSpeed says I'm 0/100 for mobile speed and 11/100 for desktop speed, with a 44.5 server response time..
GTmetrix gives me an F for my speed, recommending I serve scaled images, leverage browser caching, add expired headers, make fewer http requests, and more.
I'm trying to interpret all of these poor scores, and would like some help on how to dramatically speed up my site.
Does anyone have any tips, or know what I can do to help increase the speed and improve my scores on these sites?
That site is certainly slow, however the load times appear to be primarily from the server (I'm seeing about a 3-5s load time before the server responds with content for the home page). This has nothing to do with how many images you are loading, it probably means you have a really slow plugin or piece of code.
I'm not sure how technical you are, but I'd recommend profiling your code. An easier solution may be to disable your plugins one-by-one until your site suddenly loads faster. Then re-enable every plugin except the last one to be disabled, and verify your site still loads fast. If it does, then the disabled plugin is likely the issue.

Wordpress Running slowly

My wordpress site has suddenly started to run stupidly slowly and the only thing that has changed is the header of the site. I placed in a new photo slider and just moved the twitter feed. So i thought it would have something to do with this but the speed of the site is still slow when i disabled them both.
Which makes me think that it is a problem with wordpress or that i've taken something out of the header that i wasnt meant to.

Any help would be brilliant
Thanks
According to the Network tab on Chrome's inspector & Pingdom, the majority of your loading time is waiting for your server to respond. Could just be extra latency from accessing a UK host from the US, or your server might be overloaded with a zillion other sites.
Try tinkering around with the W3 Total Cache plugin, but if that doesn't help you might need to call your host, upgrade to a better server, or change hosts.
Also: You're loading jquery twice.

Drupal 6 website is very slow

I've made this website for someone a while ago, using Drupal 6. The problem is that it's getting incredibly slow... When I optimize the database it seems to go faster for a while and then it's slow again... I tried almost everything that I found on Google, and nothing seems to work. Maybe someone here knows a bit more than Google? :p
One thing I noticed using PageSpeed, is that some of your images on this page (http://heuvelfolies.be/CMS/Producten) are resized using HTML and CSS, rather than displaying thumbnails. Not related to your db issues, but overall it will help with page loading.
Example output:
http://heuvelfolies.be/img/Producten_Netten.jpg is resized in HTML or CSS from 360x360 to 100x100. Serving a scaled image could save 74.7KiB (92% reduction)
Are you using other caching techniques such as Memcached? Drupal caching would be step one, which you mentioned you did, but the next step would be an intermediate caching system. I've had great luck with it.
UPDATE: Doesn't look like your host provides VPS so this would be something to do if you ever moved to a VPS. Having said that, being on a shared server has its limitations. Not knowing what the "other guys" on the server are running that may be slowing the whole thing down, is one of those limitations.
Are you using Drupal's built-in caching?
If not, turn it on -- it can make a big difference.
You may also want to look into a server-based caching solution such as Varnish.
What modules are you using?
It's possible that you're using a module with known issues. Google for speed problems related to the various modules you're using.
Are you displaying any dynamic content on every page?
This can slow things down, as dynamic pages can't be cached. Consider using AHAH or AJAX to load the dynamic parts of the page via Javascript after page load, so they are separated from the main page content, which you can then cache properly.
I can't event ping that server. Maybe you should consider changing a hosting?
Other things worth checking are cache enabled, JS and CSS file merging enabled. If layout consists of many graphics, consider using CSS sprite. Also make sure that connection to your DB is fast.
Before trying to improve anything, check the "Recent Log Entries" on the admin page.
There are so many reasons for a site being slow, first try to make sure that there's no errors.
I've just had a look at your site, it wasn't particularly slow, nor fast. Pages didn't seem to hang but thumbnails were not loading so quickly.
Check your site's health, check your hosting provider, look into caching, for solutions like Varnish, you will need Pressflow or Drupal 7 as well as root access, meaning at least a VPS...
