As if the resource cache has been cleared

I currently host various site within MODXcloud, that seem to experience some sort of cache issue?

A resource within the site will load instantly (500ms) after the first visit. However, every so often various resources will again load very slow (3 - 5 seconds), as if the resource cache has been cleared. All resources should constantly load fast once they have been cached, right?

I first thought it was the MODXcloud's rolling backup that was clearing the cache, although now it's more ofter than every 24hrs.

I've added [^t^] [^s^] to the header of each resource to check total load time and source for each resource.



Total load time stays almost the same whether the resources load fast or slow! Also the source always states it's from the cache, unless I clear the cache manually.

I've enabled database cache and database session cache. I've also installed cachemaster extra.

I also use MaxCDN Toolkit extra, however, this issue was evident before I installed MaxCDN.

Any ideas what I may be doing wrong or what could be causing this issue.

I have have found the cause of the issue.
All resources using a template and static resource with the extra TwitterX installed.

This is my TwitterX call (consumer key, secret and token info removed):


Cache set at 7200 is inline with cache clearing issues / slowness that the site was experiencing?
After removing TwitterX all resources load instantly.

Should TwitterX be called cached or uncached?

TwitterX uses the MODX cache for speed so can be called cached or uncached. Only need to use Un cached if you are using the output filter :ago or similar on the date.

One thing to note is that you can try specify a cache_id which might help as otherwise TwitterX tries a generic cache filename.

Try adding cache_id='SOMETHINGUNIQUE'
