Support » Plugin: P3 (Plugin Performance Profiler) » Standard Results

  • Resolved lup0z


    I’ve installed the P3 plugin to test a WP website that it’s too slow about pages loading (according to the hosting service, the server hasn’t got any problem).
    Now I’ve got P3 results but would like to compare them with standard results on each test: where can I find them?

    Thank you so much!

    Hi lup0z,

    P3 will only compare your site’s performance relative to itself. It should help you detect changes in performance (e.g. when you install a new plugin), but it won’t tell you that your site is performing fast or slow.

    There are a few reasons for this, but the big two are:

    1.) You should decide what fast / slow are. For example, a news site, with mostly static content, high traffic, and a high percentage of mobile visitors will have different requirements than a dynamic BuddyPress site that’s used on a company intranet. You can use Google analytics or new relic to get real user metrics (abbreviated RUM) to see how fast your site loads for your users and you can experiment from there.

    2.) You can use a few other tools like pingdom tools, webpage test, yslow, and google pagespeed to collect various speed scores for how your site renders in the browser. P3 will not know, for example, how many CSS references you have, or how long your javascript/ajax takes to render in the page, or many bytes are downloaded to the client (and how long that will take over a DSL connection).

    What these tools will do is say “your site takes 500ms to respond initially” (called time to first byte or TTFB) then will go into the other static resources. P3 will tell where those 500ms are spent in that TTFB metric. E.g. 30% of your TTFB is spent in plugin X, and 25% is spent in plugin Y. There are exceptions, and these numbers won’t always line up exactly, but that’s roughly the right way to think about it.

    I hope this helps answer your question! I’m sorry the answer isn’t very straightforward.

    Hi Kurt,
    thank you so much for your reply.
    After reading it I went further with other plugins and that’s what I’ve done:
    – correct reccomendend notifications with theme check
    – I installed “Log Deprecated Noticies” and didn’t show anything bad. It says it’s all ok.
    – I used Debug Bar to check pages and things sound good: any strange notices and good queries timing.

    but the website loading is still too slow. At least 5 secs to load and sometimes almost 10.

    I ran GTmetrix too an this is the result: pdf

    Can’t understand what’s the problem. Is there any other tests?

    Maybe is more comfortable for you to check the link directly: GTmetrix test

    Hi lup0z

    Page load time: 1.97s
    Total page size: 213KB
    Total number of requests: 22

    You’re already pretty fast here.

    I saw that you left W3 Total Cache’s debug mode on, though. I would recommend turning that off immediately.

    While you’re in W3 Total Cache, please make sure you’ve updated it to the latest version 🙂

    W3 Total Cache: Minify debug info:
    Engine: disk: basic

    I would recommend looking at enhanced disk caching as it bypasses php altogether and can probably cut out an extra 100+ ms on your TTFB (again, depending on a number of factors).

    Thank you Kurt.
    So can we say that the slow speed is a server side problem?

    Ah I forgot to link the website I’m working on:

    While loading the first page at the website seems loading good (the content is quite simple though) but when accessing at all become slower.
    Even on the back end the loading time is very low.
