Change Browser limit for maximum http connections per server

Saturday, July 18th, 2009

To test performance issues with different settings of maximum allowed concurrent http connections per host, you can change the default browser settings (IE: 2; Firefox: 8) like this:

For Internet Explorer running on Windows, change the registration key, e.g.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings]
“MaxConnectionsPerServer”=dword:0000000a

This will set the number of concurrent connections per server to 10

To change the Setting in Firefox, open about:config and change the value of “network.http.max-connections-per-server”
