Re: [Speedycgi-users] Slow SpeedyCGI response / multiple parallel requests

[Sam H. <sa...@da...>]

Three backends might be OK - it probably depends on your web browser and
how many requests it makes in parallel.  Usually the number of backends
will increase to be the same as, or a little more than the number of
parallel requests going on.

I can't think of anything unusual about img tags that would break anything.

When you're looking at the backends in ps, are they changing process
id's, or are the pid's constant?  If the pid's are changing quite a bit,
then there's definitely somthing wrong there.  The same backend processes
should be handling the requests over and over, if all is working well.

You could try running truss or strace on the backends to see what they're
doing - you might get a clue there.
