P3 (Plugin Performance Profiler)
[resolved] Am I reading the stats correctly? (4 posts)

    Apologies if this is a stupid question or one someone else already asked, but I want to check I'm reading the P3 stats correctly.

    I know from pingdom and other tests that average page load times for my site are around 2-3 secs on average.

    But when I run P3 It tells me that the total load time for current plugins is 0.739seconds, = 75.6% of my page load time.

    If circa 0.75 secs is 75% of my page load time, that would give me an average page load time of 1 sec, which I know is wrong according to pingdom and other tests mentioned above.

    Am I reading that wrong, or is there some other explanation for the anomoly? Be good to know, thanks.

    P3 is measuring the load time for the php part of your page. It's going to be that first hit on the waterfall on pingdom (excepting any redirects).

    Pingdom also counts all of your other resources (images, css, javascripts) and P3 does not.

    P3 will also have some 'fudge factor' built in since it runs as a logged in user and it's doing some heavy processing. It does the best it can to account for this (see the 'profiling time' metrics and documentation), but it could still off from pingdom's metrics a bit. Pingdom will also be measuring network time, dns, etc. and P3 does not take these into account -- just server time.

    I hope this helps.
