Thanks to all who replied, I found your comments very
interesting. I'll comment on some things.

I was thinking of the same kind of reply, using cars as
a comparison. It is also a matter of budget. Think of a
guy who runs a small building business. He may have
enough money to buy a luxury car, but he won't carry
his everyday tools on it. Insted, he shall buy a van for
working and a less expensive car for personal / family use.

Hmm, I somehow disagree. If svn is supposed to be
quite resource efficient, as opposed to the more
bloated alternatives, why not provide some system
configuration range patterns depending on the
number of developers?

these are my figures. btw, how can i know the NIC specs? :
* srv-peat-svn : (old machine)
root@srv-peat-svn:~# hdparm -tT /dev/hda4
/dev/hda4: (ext3)
Timing cached reads: 424 MB in 2.00 seconds = 212.03 MB/sec
Timing buffered disk reads: 68 MB in 3.02 seconds = 22.55 MB/sec
root@srv-peat-svn:~# hdparm -tT /dev/hda2
/dev/hda2: (ext2)
Timing cached reads: 492 MB in 2.01 seconds = 245.35 MB/sec
Timing buffered disk reads: 66 MB in 3.00 seconds = 21.99 MB/sec
* bub : (new machine)
bub:~# hdparm -tT /dev/sda5
/dev/sda5: (ext3)
Timing cached reads: 1710 MB in 2.00 seconds = 855.07 MB/sec
Timing buffered disk reads: 114 MB in 3.04 seconds = 37.47 MB/sec
bub:~# hdparm -tT /dev/sda7
/dev/sda7: (ext2)
Timing cached reads: 1740 MB in 2.00 seconds = 869.64 MB/sec
Timing buffered disk reads: 194 MB in 3.01 seconds = 64.54 MB/sec

impressive. however, i can't figure out why would anyone use
virtualization to run a server. i am not saying it is not correct, it's
just i'd never consider it.

power / system failure. how to turn on indexing?

thanks for the figures
