I've tried compiling & running a LARGEPAGES kernel on my PC. Hardware:
K6-III 350 MHz, 128 meg RAM, compiling on a Seagate SCSI-2 disk on a
DPT Smartcache III PCI controller.
Here's what I have for results:
compile GENERIC: user system real
------------------------------------------------------------
4MB patch 10m35.710s 0m38.686s 14m17.171s
normal 10m26.632s 0m34.549s 14m15.473s
No difference! Is the LARGEPAGES patch intel specific? To generate
my kernel, I just copied DR-EVIL.4MB and changed it to load my kernel
config. I also tried lmbench to see if there was any improvement, and
there was no apparent difference between the largepages & standard
kernels. Each compile of GENEREIC above was done after a reboot.
