Re: numbers don't lie ...



here are a bunch of new numbers:
make: dell 2950
OS: Freebsd 6.2-PRERELEASE
cpu: XEON 3.20GHz dualcore * 2
memory: 4GB

no swap configured/used.

make buildworld -j 8:

src & obj real user system hyper
-------------------- --------- ---------- --------- -----
Dell PERC 5/i RAID 0 24m17.73s 1h4m31.49s 15m47.44s no
Dell PERC 5/i RAID 0 22m3.39s 1h38m46.84s 28m54.18s yes
iSCSI/netapp 26m49.98s 1h4m26.77s 16m12.89s no

src obj
--------------------
md Dell PERC 5/i 24m7.22s 1h4m44.94s 16m24.45 no

so, if numbers are to be believed:
1- hypert helps in the real time, but user and system are bigger.
allot of sweat for a very small gain.
2- src in memory made no change.

could it be that the src three was already in the memory, cached? or did
you do each test after a reboot?

3- slow disc (iscsi) vs. very fast disk (PERC 5/i RAID 0) - about 1:3 speed,
produced
less than 10% gain in time.
