Cache store performance reporting

Hello friends,

Could anyone please explain me what exactly values which are displayed in this report mean?

As far as I understood from the context of some forum discussions, the lower those values are, the better the performance, but what are those numbers?

Our Moodle works quite slowly, and our results look like this:

Cache store performance reporting - 100 unique requests per operation.

Store requests when used as an application cache.
PluginResultSetGet - HitGet - MissDelete
APC user cache (APCu)Invalid plugin----
File cacheTested15.99670.68080.08501.0973

Thanks in advance!

I'm also asking the same thing here: https://moodle.org/mod/forum/discuss.php?d=376713#p1573660

My gut feel is that these are "duration in seconds, per cache operation". Which means that a single "set" in your file cache takes almost 16 seconds, so there is something wrong with your file cache directory/filesystem.

Disclaimer: It is just my guess. That page has no explanation as of Moodle 3.7.

Correction: "It is the time, in seconds, to run the SPECIFIED number of requests." (not per request) https://moodle.org/mod/forum/discuss.php?d=376713#p1573666

Why would one have larger numbers then while use memcached in comparison to file cache?
