If you use /dev/poll, the setting of FD_SETSIZE doesn't matter.

Which operating system and version are you using.  I guess it's
Solaris, but I'd like to be sure about it, and would like to know the
OS version.  How many CPUs are available on your machine, and how many
threads is named using?  If you disable threads, does that provide
reasonable performance without other problem?
