Subject: disk throughput down in 2.5.8
Date: Fri, 19 Apr 2002 01:36:36 +0200 (MET DST) [thread overview]
Message-ID: <200204182336.BAA22417@harpo.it.uu.se> (raw)
Is it just me or is disk I/O throughput way down in 2.5.8?
I was preparing to build 2.4.19-pre7 on a box running 2.5.8,
when I noticed that 'tar zxvf' on the kernel tarball seemed
slow and jerky. So I ran
cd /tmp; time tar zxf /path/to/linux-2.5.8.tar.gz
on several boxes(*), comparing 2.4.19-pre7 with 2.5.8.
On the older boxes (2 PentiumIIs and one K6-III), 2.5.8 was slower
by factors of 2.3-4.5. A P4 with an IBM 60GXP "only" suffered a
40% slowdown.
