well, that’s … unexpected š
could you do a 5-run (amount can be chosen under “advanced settings”) test on webpagetest.org and post the 2 result-urls here so I can compare what is happening?
Here you – is this what you mean?
https://www.webpagetest.org/result/161113_QP_R4S/
Thanks for the help.
Andrew
well, that’s a start (W3TC minification, right?), but to be able to compare I would need to also see the version with AO (without W3TC) and one with both AO & W3TC minification active? š
Hello Frank,
Here is the link to testing with AO fully on, W3TC on but with minification set to disabled.
https://webpagetest.org/result/161114_50_DYQ/
With the above settings in gtmetrix the pagespeed score drops by about 30% but the Yslow score only drops by about 5%
Thanks – Andrew
ok, so we now have a test where W3TC does minification and one where AO does, can you do the same test where both are minifying (as that’s when you say you get the best results)?

Hello Frank,
Thanks – some confusion though. The results I sent you yesterday are the ones where ‘both’ options for minification are on.
https://www.webpagetest.org/result/161113_QP_R4S/ (all on)
https://webpagetest.org/result/161114_50_DYQ/ (AO on, w3tc minification off)
I’ll do another now with AO off.
Thanks
Andrew
ok, so comparing the most important metrics of those 3 tests;
ao+w3tc ao w3tc
first byte 0.750s 0.193s 0.344s
start render 2.164s 1.508s 3.701s
doc complete 3.731s 5.266s 4.463s
Based on these, the only problem when running only AO minification is your time till doc complete. When zooming in on that test-result, it seems like the autoptimized JS-file is not gzipped (whereas the CSS-one is, which is weird, probably a conflicting Apache setting). So try disabling the “static delivery”-option of AO, this will result in the autoptimized CSS/ JS being delivered by PHP-code which will ensure both the CSS & JS are gzipped. I’m pretty convinced AO will win hands down š

Thanks for the feedback Frank.
It’s a bit beyound me:-) So, do you recommend keeping both minifications on (AO and w3tc) but just adjust the static delivery setting of AO?
Thanks again – Andrew
I would switch AO to non-static file delivery and to another webpagetest with the AO-only setup to confirm š
Here is the result with AO static delivery disabled and w3tc minify disabled.

somethings broken there, 404’s on multiple requests, even ones for W3TC-minified CSS/ JS. guess you might have to purge your W3TC cache …
Strange – I have purged the cache multiple times but still get a 404 only on repeat view?
https://www.webpagetest.org/result/161114_7T_NAM/
When I turn AO static back on I get repeat view error of 403?
https://www.webpagetest.org/result/161114_FH_NDG/
did you also purge w3tc cache? because it looks like that’s the problem actually; your w3tc pagecache seems to holds old HTML?
