SSL TPS verus SSL connections

All,   can anyone explain (or point me to a link with an explanation) SSL TPS versus SSL connections. I've been asked to provide peak & average SSL TPS more accurately than the inbuilt F5 graph....

Connections != TPS.

 

 

Connections == the number of concurrent connections.

 

TPS == the number of NEW connections per second

 

 

Be aware that the F5 counts TPS's very harshly... It's not actually licensed in transactions or connections per second. It's actually limited to TPS/100 per 10ms... So if you have a 100TPS license, you can only have 1 connection in a 10ms window. For a 1000TPS license you get 10 connections in a 10ms window. Any more will result in a license violation and a dropped connection (Even though you haven't gone over 100 transactions in a second).

 

 

See soln 6475 for the details (http://support.f5.com/kb/en-us/solutions/public/6000/400/sol6475.html)

 

 

A good rule of thumb is that the peak SSL TPS's is about 2x the 60 second average...
