Resolved [17.8.11 Update #30] - enable keep-alive

[futureweb]

Hey there,
how can I enable keep-alive on a specific Hosting in Plesk Onyx?
nginx is deactivated - just apache is used!

already tried:

<ifModule mod_env.c>
SetEnv KeepAlive On
SetEnv KeepAliveTimeout 100
SetEnv MaxKeepAliveRequests 500
</ifModule>

<ifModule mod_headers.c>
Header unset Connection
Header set Connection keep-alive

Header unset Keep-Alive
Header set Keep-Alive timeout=100,max=500
</ifModule>

But it still sends "close" on Connection ....:



keep-alive test telling me it's deactivated: Is Keep-Alive Enabled Checker

any ideas on that?

thx, bye from Austria

Have you tried these methods TTFB for site is too high in Plesk. What can be done to improve it? ?

IgorG - and once again you made me look stupid
Searched quite some time for this Info and wasn't able to find it (always found the WINDOWS Plesk only Version of it) ... thank you! ;-)

keep-alive is now enabled - also some other things like Browser-Caching, GZIP, ...

But sometimes the Site in Question still has a VERY BAD TTFB - escpecially when it's called the first time after it hasn't been called for a few minutes. On the second load the TTFB is ok ... (browser caching disabled of course)
Are there any more tweaks you could think of for enhancing TTFB on initial Page Load?
(seems like apache or php 7.2 is slow spawning the first time it's called?!?)

Site in Question: EDV Dienstleister Fieberbrunn und Umgebung - EDV Service von Profis

Actually, there are many possible reasons except Apache settings. Slow MySQL, for example. Try to check these suggestions for optimization Troubleshooting slow websites

Time is cut in half on second request. Unfortunately it's no Web-Page from us - our Hosting Customer just told us "the Page is slow on our Server and fast on other Servers" ... that's why I started investigating ... if it's really a Server issue of our Shared Hosting Server. Or if it's just the Page which is slow.
Will do some further Tests.

thx
