slowing down after 1000 connections

[avis03]

Hey, I am running this on a server which is hosing my website freeimagehost.eu.
For some reason when connections start to go over 900-1000, the site starts to go really slow and sometimes image pages such as http://www.freeimagehost.eu/image/9167612336333 dont even load all the way, they load halfway and then stop. also, the site goes way too slow after that point to navigate. can u please tell me what is wrong? since anything below 700 connections, it works like a charm. thanks


ps, would it be possible if i give you access to the server and you can take a look at it in there and see whats wrong? that would be great. thanks.

Are you using LiteSpeed Enterprise or Standard edition? The free standard edition is not designed to handle the the traffic load you are describing.

check your ip_conntrack setting


To print current limit type:
# sysctl net.ipv4.netfilter.ip_conntrack_max



To increase this limit to e.g. 100000, type:
# sysctl -w net.ipv4.netfilter.ip_conntrack_max=100000

Alternatively, add the following line to /etc/sysctl.conf file:
net.ipv4.netfilter.ip_conntrack_max=100000

The following will tell you how many sessions are open right now:
# wc -l /proc/net/ip_conntrack
