Improving MODX Performance

I am really struggling with the performance of my website, with it taking 3 seconds to display each page. I believe that the problems lies with the fact that i have a right column structure which is made up of a series of sections that the content editor can define/select. I have done this by placing a call to a TV in my template [[*submenu]]. The TV *submenu, defined as a checkbox, has a call in the 'input options values' field to a chunk, i.e Yes==[[$submenu]] - the chunk will either use getresources to get the content from a resource, have static code in it, or use wayfinder to generate a submenu. This allows the editor to use a series of checkboxes to define the content of their right column on a per page basis.

However............this is obviously having a bit hit on performance, so is there a better way to do this?

Thanks for any tips

what is the content of your chunk submenue? Your code?

Well, i have about 10 of the TVs called from the template, each TV calling a different chunk, below are some examples of what the chunk code is for the chunks called by these TVs:

Example 1


Example 2


Example 3


Example 4


my concern is that although the TVs are called from the template, if the check box on the resource is not checked by the content editor, then that TV is not displayed - could this be causing the slowness?

Thanks for taking a look

Is it slow only the first time, before it is cached, or is it also slow after the page has been cached?

unchecked (empty) TV - values shouldn't make performance - issues.

But you can try it out by removing all TVs and put some of your chunk - codes directly into your template, if that makes any difference.

Can't you put all chunk-tags into the inputoptions of one checkbox-TV?

Might also be worth checking your system ram, Revo recommends 64Mb of allocated ram to run optimally. I have had other sites on smaller servers that had some performance issues when the allocation was set lower.

Hi, thanks for your responses - Bruno17 you were absolutely right, not sure why i hadn't put all the chunk tags into the same checkbox TV!!! I have done that now though and also found an uncached submenu call which has definitely improved things on the second time a page is visited (less than a second), but it is still a good 2-3 second delay the first time a page is displayed - not sure if there is anything i can do about that now though is there?

Will have a look at system RAM Charles, thanks for info....

Hi Emily

have you read this thread? give-modx-some-speed
There are some general hints to speed up MODX.

I would also suggest looking into http://modx.com/extras/package/xfpc, granted if your server is overloaded that can also delay things. I would make sure you have a solid hosting provider.

Thanks for all your comments folks - i have installed xfpc and it makes a huge difference on cached pages, amazing ! It still take a couple of seconds to load each page for the first time, but definitely better than it was

I'm glad to hear xFPC helped with the load issues, however it still shouldn't take that long for the initial load. If you could tell us more about your hosting, and what addons you are using we can reduce the load time further.
