Page load performance

[mbrando]

Hello,

I have web site that we moved to a new VPS with 4GB memory and 60GB SSD storage.
The site about 30 to 50 concurrent connections if you run netstat. However, When I run tools like

http://tools.pingdom.com/fpt/#!/c8Nt1B/ ... hcsmm.org/

There is this 2-4 second browser wait while the server is doing something. It looks like it is not mysql related, but rather a CPU intensive task that is causing load issues on this server.

I'm not sure how to figure out what is the cause of the 2-4 browser wait. I asked the Techs at the Data center to look and they say it is a php process on the account above but cannot see what the process is doing specifically.

Any thoughts on where to start this hunt?

Anyone ever use strace to trace a process?

It generates a mountain of info. How did you make heads or tails?

I had same error and found that I had issues with my Joomla.

Timed out...

I made a few changes and resolved the issue but yours might be different.

Hello,

So I looked at gtmetrix.com is has much of the same info that tools.pingdom.com was showing.



So I'm going to try this to see what the heck joomla is doing for 2-4 seconds while the browser is waiting for page data.

newrelic.com

It Looks promising. Here is a snip from their propaganda:

New Relic Insights

With it you can quickly and easily create real-time dashboards to get immediate answers about end-user experiences, clickstreams, mobile activities, and server transactions.

Hello,

Well, I think I found the bottle neck. The /ContentController/display call is taking from 4 to 20 seconds to display. I'm sure some of that is load related, but also making a load issue at the same time.

Now, how would I go about addressing /ContentController/display this issue? See attached screen grab.

Hello,

More specifically it looks related to these calls:

JControllerLegacy::execute

that runs

ContentModelArticles::getItems - 8,830ms duration

Hi. Please, remove SEF in Joomla, if you use cache remove cache and test again.

I have same problem. Joomla 3.3.3 very slow when i use SEF. I try con Joomla SEF, Artio and MijoSEF.
