Subject Perchild on Solaris (was: Perchild works again.... kind of)
Date Tue, 20 Aug 2002 02:07:37 GMT
On Solaris, this macro definition is required to build successfully:
  -D_XOPEN_SOURCE=500 -D__EXTENSIONS__

By the way, with the perchild MPM, httpd performance is
"T2 (alternate) thread lib < T1 (default) thread lib".

By contrast, with the worker MPM, "T2 thread lib > T1 thread lib"
(But the difference is smaller than the perchild MPM).

With the perchild MPM and the T2 thread lib, mutex contention
may cause performance penalty, I guess...
