I'm about to send change-request to Apache to change default configuration
on NetBSD to something more performant. I've added USE_SHMGET_SCOREBOARD,
USE_MMAP_SCOREBOARD and HAVE_MMAP to src/include/conf.h and 
I am considering to add USE_MMAP_FILES. 

I recall a discussion some time ago about heavy use of mmap() actually
_decreasing_ performace of reads from mmap()ped files. I don't
remember correctly (I'm no expert in this ;), can someone confirm 
(or displace) it ?

Second thing: are (or have been) there any known problems with our
regex ? I'm considering to change default configuration to use
system regex instead of HSREGEX.

Thanks in advance
