Subject: performance improvements
Date: Mon, 23 Dec 2002 16:32:26 +0100	[thread overview]
Message-ID: <200212231632.26686.russell@coker.com.au> (raw)

One thing that could really improve system performance would be something like 
"nice" but for disk IO.

If you have a server that's using 90% of it's disk bandwidth with a large 
number of clients (EG a big mail server) then a simple "find /" is usually 
enough to give it a load average of 50+ and a delay of 1 second for every 
disk request (which makes operations such as POP mail checks excessively 
slow).
