Subject: swapout bandwidth
Date: Wed, 31 Jul 2002 01:15:09 -0700 [thread overview]
Message-ID: <3D479C8D.1DAB44D1@zip.com.au> (raw)
Seems poor. On mem=512M, with 30 megs/sec of swap
bandwidth, a
memset(malloc(800megs))
takes 21 seconds, and 16 on 2.5.26.
There are big latencies during this too (vmstat freezes for
many seconds). But I seem to have fixed that in the
pagemap_lru_lock patches. Not sure how though ;)
