Hi Ashish,

Take a look at SAIO: http://swift.openstack.org/development_saio.html (http://swift.openstack.org/developmen...)

I'm not a tcp expert, but as this configuration seems to be used at rackspace, i suppose it doesn't cause much problems in a swift environnement, even under high load. If you think it's a bad idea to use use those parameters, perhaps you should convert your question into a bug ?

Hi Kunal,

Did you follow the tuning guide for swift ? http://swift.openstack.org/deployment_guide.html#general-system-tuning (http://swift.openstack.org/deployment...)

disable TIME_WAIT.. wait..

net.ipv4.tcp_tw_recycle=1 net.ipv4.tcp_tw_reuse=1

disable syn cookies

net.ipv4.tcp_syncookies = 0

double amount of allowed conntrack

net.ipv4.netfilter.ip_conntrack_max = 262144

Hi,

I'm trying to set up slogging, it seems to be ok but i'm getting a 499 error when i'm trying to upload this logs :

All seems to be ok except the object upload.

Could someone help me ?

2011-06-01 10:12:24 -0600 asked a question [documentation] "net.ipv4.netfilter.ip_conntrack_max" is an unknown key

The value "net.ipv4.netfilter.ip_conntrack_max" specified in the documentation ( http://swift.openstack.org/deployment_guide.html (http://swift.openstack.org/deployment...) ) doesn't seems to exist anymore. "net.netfilter.nf_conntrack_max" looks like the replacement value. Could you confirm that, and eventually modify the documentation ?
