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 _________________________________________________________________ http://clk.atdmt.com/UKM/go/197222280/direct/01/ Do you have a story that started on Hotmail?
