MODx speed and optimisation

I’m finding both the MODx manager and the site it creates to be a bit sluggish. The site itself is about 50 pages and all normal stuff - mostly text - using Ditto to aggregate some news, the Breadcrumbs snippet and Wayfinder for the menu. It varies but sometimes it can take over 5 seconds for a page to load and it is similarly sluggish when using the Manager.

Are there any simple things that I could do - or maybe should avoid doing - in order to get a better response speed?

Also, is there a way of analysing the speed of a server in order to eliminate this as a factor?

That sounds incredibly, terribly out of character. The modx site itself is thousands of pages and runs on a very modest server and doesn’t render that slowly.

What version are you running, and what plugins are your running?
Are you using caching?
Have you put the timing indicators in the footer to see which bit is taking a long time?
Have a link to your site?
Where is it hosted?

The version is 0.9.6.1p2.
The only plugin I’m using is TinyMCE (I’ve disabled QuickEdit) and I am using caching.

I’ll put the timing indicators in the footer and see what that yields.

Whilst looking up the version etc, I managed to get a PHP Parse Error - I don’t know if that has anything to do with it.

MODx encountered the following error while attempting to parse the requested resource:
« PHP Parse Error »

Error while inserting event log into database.

I’ve always found MODx to be pretty quick so I was suprised by how this particular site was behaving (especially as it’s not that complicated a site).
I’m wondering if the problem is down to the server - I’m not sure how I can quantify that though.

that error tells you that your mysql has to many open connections. So I think your mysql server (or some who over uses it) is the problem

Thanks for your help - it’s a shared server but I don’t know how it’s operated beyond that.

I put in the timing indicators and it comes up with some wildly differing times - here are a selection:

Query time: 17.7952 s, Query count: 5, Parse time: 0.0566 s, Total time: 17.8518 s, Source: database
Query time: 0.1402 s, Query count: 7, Parse time: 0.0506 s, Total time: 0.1908 s, Source: database
Query time: 0.0205 s, Query count: 6, Parse time: 0.0435 s, Total time: 0.0640 s, Source: database
Query time: 0.0249 s, Query count: 7, Parse time: 0.0694 s, Total time: 0.0943 s, Source: database
Query time: 3.5452 s, Query count: 4, Parse time: 0.0237 s, Total time: 3.5689 s, Source: database
Query time: 0.0106 s, Query count: 1, Parse time: 0.0589 s, Total time: 0.0695 s, Source: cache
Query time: 6.0333 s, Query count: 4, Parse time: 4.7058 s, Total time: 10.7391 s, Source: database
Query time: 35.1784 s, Query count: 4, Parse time: 0.0224 s, Total time: 35.2009 s, Source: database
Query time: 3.0845 s, Query count: 1, Parse time: 0.0451 s, Total time: 3.1296 s, Source: cache

Sounds like a badly overloaded shared server. Some of these can have 400 or more sites on the same server.
