It's not very high but twice as much what we have on Squid at the same time. Thank you for your link, we actually use the same sysctls than for Squid - that is, default values for everything except : net.ipv4.ip_local_port_range = 1024 65535 vm.mmap_min_addr=4096 vm.swappiness = 40 > Regarding half the traffic, just check whether you have failed requests (e.g. > "varnishncsa -m TxStatus:[45]" or similar), but it can be due to the way > Varnish handles keepalives differently (what are your Varnish vs. Squid > settings for Keepalives?). We have a lot of 304 (not modified, I assume this is normal) and some 404, not enough to worry about so it seems to work. Considering keep-alives, we have the default for Varnish : default_grace 10.000000 [seconds] default_keep 0.000000 [seconds] default_ttl 120.000000 [seconds] sess_timeout 5 [seconds] sess_workspace 65536 [bytes] session_linger 50 [ms] session_max 100000 [sessions] And for Squid, we have : pconn_timeout 60 seconds request_timeout 5 seconds half_closed_clients off client_persistent_connections on server_persistent_connections on Let me know if you need any other values. _______________________________________________ varnish-misc mailing list [email protected] https://www.varnish-cache.org/lists/mailman/listinfo/varnish-misc
