Re[2]: how to break out of FCGX_Accept_r - multi-threaded fastcgi performance

Hello Emil,

Thanks for the reply. This more or less confirms the issue. But maybe
it's a mod_fastcgi issue because external servers do not have that
problem.

Now I have three questions:

1. For external servers, how to you manage running/restarting the
servers? mod_fastcgi does that nicely. I suppose you write your
own scripts to monitor the external servers?

2. External servers would use sockets. How does it affect performance
compared with domain socket?

3. has anyone had good experience for multi-threaded fcgi apps
with the other Apache fastcgi module, what was it called again -
something like lib_fcgi?

Best regards,
Jack
