Hi Rmkml, This is dell pe1850. single cpu (hyperthreading). Not too many diskio (as the cache is only 6gb and 512ram cache) (I have 2gb of ram, 3.2ghz cpu) iptables is configured. ( I can drop this for testing) Heartbeat is running (2 boxes) dnsserver for squid is running Kind Regards Michal Mihalik cat /proc/interrupts CPU0 CPU1 0: 157 270583168 IO-APIC-edge timer 1: 0 8 IO-APIC-edge i8042 4: 0 8027344 IO-APIC-edge serial 8: 0 0 IO-APIC-edge rtc 9: 0 0 IO-APIC-level acpi 12: 0 96 IO-APIC-edge i8042 14: 0 74 IO-APIC-edge ide0 169: 0 0 IO-APIC-level uhci_hcd:usb1 177: 0 6180176 IO-APIC-level megaraid 185: 0 0 IO-APIC-level uhci_hcd:usb2 193: 0 0 IO-APIC-level uhci_hcd:usb3 201: 0 343508884 IO-APIC-level eth0 209: 0 20 IO-APIC-level ehci_hcd:usb4 217: 0 251486493 IO-APIC-level eth1 NMI: 0 0 LOC: 270593401 270591920 ERR: 0 MIS: 0 My squid.conf http_port 80 icp_port 0 hierarchy_stoplist cgi-bin ? cache_mem 512 MB maximum_object_size 32 MB maximum_object_size_in_memory 48 KB ipcache_size 1024 fqdncache_size 1024 fqdncache_size 512 cache_replacement_policy lru memory_replacement_policy lru cache_dir aufs /var/spool/squid 6000 16 256 cache_access_log /var/log/squid/access.log cache_log /var/log/squid/cache.log cache_store_log none pid_filename /var/run/squid.pid debug_options ALL,1 redirect_rewrites_host_header off request_body_max_size 15 MB refresh_pattern ^http: 0 20% 4320 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 negative_ttl 1 seconds positive_dns_ttl 15 minutes request_timeout 30 seconds persistent_request_timeout 10 seconds acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl lan_192 src 192.168.0.0/255.255.0.0 acl to_localhost dst 127.0.0.0/8 acl purge method PURGE acl smeFarm dst 217.67.20.139 192.168.0.2 85.248.69.139 192.168.0.5 192.168.0.4 http_access allow purge lan_192 http_access deny purge http_access allow manager localhost http_access deny manager http_access deny !http_port http_access deny to_localhost http_access allow smeFarm http_access deny all http_reply_access allow all httpd_accel_host virtual httpd_accel_port 80 httpd_accel_uses_host_header on logfile_rotate 0 memory_pools_limit 100 MB client_db off buffered_logs on strip_query_terms off coredump_dir /var/spool/squid > -----Original Message----- > From: rmkml [mailto:rmkml@xxxxxxx] > Sent: Monday, March 27, 2006 5:13 PM > To: Michal Mihalik > Subject: Re: squid performance epoll. > 350req/sec 100% cpu > > Hi Michal, > maybe send to list /proc/interrupts ? > Regards > Rmkml > > > On Mon, 27 Mar 2006, Michal Mihalik wrote: > > > Date: Mon, 27 Mar 2006 17:31:36 +0200 > > From: Michal Mihalik <michal.mihalik@xxxxxxxxxxxxx> > > To: squid-users@xxxxxxxxxxxxxxx > > Subject: squid performance epoll. 350req/sec 100% cpu > > > > Hello. > > I am tring to optimize squid for best possible performance. > > it is in production and it's doing more than 350req/sec. > At peaks upto > > 500req/sec. > > > > My problem is only one. 100% cpu. :-) > > > > I tried to update my debian to 2.6.16 and recompiled squid: > > > > Squid Cache: Version 2.5.STABLE12 > > configure options: --prefix=/usr --exec_prefix=/usr > --bindir=/usr/sbin > > --sbindir=/usr/sbin --libexecdir=/usr/lib/squid > --sysconfdir=/etc/squid > > --localstatedir=/var/spool/squid --datadir=/usr/share/squid > > --enable-async-io --with-pthreads > --enable-storeio=ufs,aufs,diskd,null > > --enable-linux-netfilter --enable-arp-acl > --enable-removal-policies=lru,heap > > --enable-snmp --enable-delay-pools --enable-htcp --enable-epoll > > --enable-cache-digests --enable-underscores --enable-referer-log > > --enable-useragent-log --enable-auth=basic,digest,ntlm --enable-carp > > --with-large-files i386-debian-linux > > > > the thing I realy don't like is 25% cpu + 50% system cpu . > > > > why the 50% system!!!!! > > can anyone help? > > > > Kind Regards > > Michal Mihalik > > > > >
