Re: Multi-Boot
Maybe someone else out there with a bigger, more interesting, system can
add some comment...
Personally, I have the following setup:
Adaptec 2940UW
3 x 4.3 GB UW SCSI HDDs
3 x 128 MB swap, one per drive
128 MB root partition on /dev/sda
RAID-0 across the remaining space on all drives
It gets me some really good performance. I ran `bonnie' today. Here
are the numbers (see the PII/233 line), along with some other
computers' figures for comparison:
-------Sequential Output-------- ---Sequential Input-- --Random--
-Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks---
Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU
PII/233 500 3732 88.8 15087 47.7 4307 24.4 4263 90.3 17789 34.3 58.8 1.9
Sun4/260 78 285 90.9 650 26.4 305 20.0 282 95.5 803 28.3 38.5 15.2
Mips M2k 180 387 44.0 442 6.1 360 5.4 416 48.1 1701 14.8 26.3 3.1
Sequent 95 140 97.8 1017 66.2 251 17.7 122 95.7 713 34.9 31.0 15.9
4M i386 25 130 90.5 199 26.1 179 46.1 121 93.5 400 59.7 10.5 23.8
NeXT 125 241 94.7 347 39.3 253 31.7 246 94.8 772 49.6 27.7 20.8
VAX 8650 200 208 89.0 232 8.3 143 7.4 197 65.0 373 8.6 17.3 4.6
You might want to consider combining your drives with RAID-0 (or some
other level) in such a manner as well.
