hey
We are using 2 x 320GB SATA2 with reiserfs 3.6. The machine experiences high
iowait when the cache reaches cache_swap_low. What we have observed that it is
constantly stuck at cache_swap_low. If we purge the cache it starts to work
fine again until cache hits cache_swap_low mark.
We are using:
cache_swap_low 94
cache_swap_high 95
Our settup
<*> Squid Cache: Version 2.7.STABLE6
configure options: '--enable-async-io'
'--enable-icmp' '--enable-snmp' '--enable-cache-digests'
'--enable-follow-x-forwarded-for'
'--enable-storeio=aufs,ufs,null,diskd,coss'
'--enable-removal-policies=heap,lru'
'--with-maxfd=65535' '--disable-ident-lookups' '--enable-truncate'
'--enable-linux-tproxy'
'--enable-linux-tproxy' '--enable-large-cache-files'
<*> Kernel 2.6.31.13
<*> Debain lenny 5.04
<*> ~300 requests/sec
machine is setup in bridge mode with tproxy transparent, with ip configured on
br0 interface.
any help will be much appreciated.
thanks in advance
