Running at AL now 2.3.7 again, all fine again with 1-3 processes
instead of the 30+ with 2.3.8.
The config live running here and your config for synthetic test is
different. And not using fat php processes and max processes is in
place.
Not any mod_fcgid directives here in a vhost, only in server the
commonly used config for php. All vhosts here serving .php, including
the default vhost. Running server 2012.

Becoming dramatic here, already running over 30 processes. Running out
of memory this way.
All time high here is 5 processes, and while writing this mail it is
already 34 and all 34 have an entry in the mod_status page.
Also looks like it is not stopping/killing processes any more, have
entries with 1784 seconds idle (FcgidIdleTimeout is default, 300)
Going back to 2.3.7 at AL.

Observe a different behavior compared to 2.3.7
- It spawns a lot more mod_fcgid processes, looks like vhost is in
charge (mod_fcgid only global defined here)
- I see in Windows taskmanager and in mod_status 5 processes and the
error log says that the are 3 started, a mismatch.
- Also different in mod_status page, see more then one entry for
Process: php-cgi.exe
With 2.3.8 splitted now :
Total FastCGI processes: 5
Process: php-cgi.exe (d:/servers/apache/php/php-cgi.exe)

With 2.3.7 was only one entry, like:

Pid Active Idle Accesses State
3204 1962 7 187 Ready
5036 2143 17 �� 192 Ready
...
Not really trust 2.3.8 (yet), give me a few days to observe more.
Thanks, Steffen. I'll try to reproduce soon and see which commit
changed that. (Maybe 1377398?)
So far I've only set up a simple test... Simple perl FastCGI script,
ab -n 200000 -c 20, default main vhost configuration, this for the
vhost:
<VirtualHost *:8082>
FCGIDCmdOptions /home/trawick/myhg/apache/fcgid/apps/altinfo.pl \
InitialEnv VHOST=any \
InitialEnv PERL5LIB=/home/trawick/perl5/lib/perl5
</VirtualHost>
2.3.7 grows up to about 12 (vs. max 20 concurrent clients).
2.3.8 grows up to about 20.
I got both the fastest and slowest times for 200,000 requests using
2.3.8. Generally I suspect 2.3.7 is slightly faster, but I don't have
a good overall summary.
If you're using FcgidCmdOptions, I'd recommend using the MaxProcesses
parameter to something that your system can handle. Otherwise, see
FcgidMaxProcesses and FcgidMaxProcessesPerClass. Regardless of 2.3.7
or 2.3.8.
Still, for this simple scenario + configuration, 2.3.7 would have been
better (generally not worse performance, uses 40% fewer processes).
Different scenarios would have different results, but I think that the
common, fat PHP processes would have bigger problems with 2.3.8 if
there is no reasonable configured limit on the max to spawn.
Does anyone else have time to play?

Thanks in advance for testing!
