All the good stuff is im the PDFs.

1, Symptoms: Slow ssh connect, slow webpage loads, MAIN: Dev rsycn pulls dropping to low kbps on .json files and then temp lss of connection (speedtest is fine)

vmstat 1 5
free -m
ps aux --sort=-%cpu | head -15
iostat -x 1 5

this is a beauty, run from NUX/DOSBOX: pathping -n 128.199.200.202

This helped:

Live hasn't rebooted since Monday morning, so the slowness went away by itself. The single MaxClients line doesn't match today's slowness either. It's from Tuesday 10:40 server time, a day and a half ago. Your server clock also looks about 2 hours behind Sydney, so that's roughly 12:40 AEST on Tuesday.

I doubt the Tuesday hit is the KeepAliveTimeout 10 problem I raised earlier. If holding workers for 10 seconds were starving the server, you'd see MaxClients lines in clusters, not one line in about 36 hours. More likely a short bot burst filled the workers once, mod_reqtimeout and connlimit dealt with it, and the workers were freed again.

So the most likely cause of today's slowness is your carrier link, which is already about 400ms with about 10% loss and sometimes gets worse. That fits a problem that appears and disappears with nothing changed on the server.

These two commands would confirm it:

grep -c MaxClients /var/log/httpd/error_log*        # includes rotated logs: was the Slowloris period full of these, and has it been quiet since?
grep 'Sep 23' /var/log/httpd/error_log | tail -20   # anything logged during today's slow spell

If Sep 23 shows nothing unusual during the slow spell, the server wasn't struggling and the delay was on the network.

The load average is up a bit right now: 3.19 over the last minute on 2 CPUs, against 1.55 over five minutes. That's probably just whatever you're running in the ISE directory, but it's worth knowing in case the slowness comes back soon.
