Strange Slow When Caching

    I have two servers, A is 2 Cores and 4GB with openlitespeed, this plugin works well on it, it significant improved the speed; B is 4 Cores and 4GB with openlitespeed, strangely, using this plugin on it may slow the website. (Note: A and B have totally the same website content, themes, and plugins, and the same setting on the openlitespeed, database and php.)

    Here is some information on B (All data are collected using an Inprivate Page). This is when I enable the plugin but disable JS and CSS improvement.

    This is when I enable the plugin and enable JS and CSS combination and delayed. (A little slower? )

    That’s when I disable all cache function. (A lot faster? )

    the server performance could vary , the network could vary

    and some options you enabled, indeed it could slow thing down when cache miss , as it needs to do certain tasks like optimize JS/CSS and such

    But A better performance server(B) should not have a longer TTFB. The network is the same (cause A and B are in the same place), and they have totally same setting (with export and import function to do that).

    May you please point out how can I figure out what’s the TTFB are used for? (like which plugin or which function…)

    Many thanks!

    but more CPU core does not always mean better performance , unless they are dedicated cores , not over-commited , or even better, a dedicated server, otherwise I don’t really trust the CPU too much

    and yes, even network from same place could be fluctuating , one thing I would do is to curl it from server itself, this will rule out network flutuation

    if it’s cache hit request, then you can check OLS’s log

    if it’s PHP request , you can try our plugin’s log , or somethign like query monitor
