Craig,
  If your os or application is cpu cache intensive (and I can't think of any 
that aren't), you'll want to get a pipeline burst cache motherboard, and in 
addition you'll want to use EDO memory, or have a beefy L2 fast 512K cache.

Try building a new kernel.  If that doesn't work, try using Slackware
or BOGUS binaries for the net stuff.  Or rebuild them.

Why Apache?  What's it got that recent NCSA and/or CERN HTTPd's don't?

4MB of onboard cache for the SCSI host ;-).

Why "processor cache"?  Processor cache is *faster* memory.  That's
why it's expensive.  Allocating system DRAM to the processor's cache
just adds an extra memmove to the pipeline; it can't speed up access.

Just use it as RAM :-); I regularly am swapping with 32 MB :-P  I
append my current "top" and "ps ax" figures: there's not that much
running, I don't have any of my other users logged in, I'm not
rebuilding the kernel, etc etc.  Now I could recover about 5MB
instantaneously by flushing Netscrap's RAM cache, I think, and there's
something screwy going on with the crond, maybe it's leaking memory
too.  Cannaserver uses a fair amount.  But mostly, "X expands to fill
up the available RAM, and then some."  That's why we use "X" as a
variable, because it varies!

Add wings.  ;-)  The best wings are BBQed at "Buffalo Wild Wings and
Weck", 1864 N. High St., Columbus, OH, 43201.  I forget the phone
number (try Dial-104 :-), but they deliver, at least in the Ohio State
campus area.  ;-)
