Topic: Long TTFB upon first request

[uofmrob]

Hi Everyone,
I've been trying to fix an issue on my Ubuntu 16.04 web server for some time. I've tried all of the fixes that I could find and nothing seems to help.

Basically, I've got an Apache 2.4 web server running with a half dozen or so virtual hosts with different domain names, some running PHP sites, some running straight HTML, and others with just a single HTML redirect.

When you first go to any of the sites, the time to first byte is at least 20 seconds, then any accesses after are instantaneous. If you open a site in Chrome, the TTFB is 20 seconds, followed by fast access, then if you try to open the same site in Firefox, again, the TTFB is 20 seconds, followed by rapid access.

I've added my domains to the /etc/hosts file, added the computer's hostname to 127.0.1.1, disabled .htacess temporarily to see if something there was causing the issue, tried http and https, so it's not an SSL issue, disabled HostnameLoookups and several other things that have worked for other people. I've looked at the apache error logs and nothing seems to pop up. There's not much traffic on any of the sites, so I don't think that it's a workload problem or anything (typical server load is around 0.02).

I'm hoping that someone can point me in some new directions for things to try to diagnose and fix the issue.
Thanks in advance!
Rob

Can you provide a screen shot of the network analyses from chrome? Or provide an url for testing.
