Has anyone carried out any channel access performance tests?, comparing
performance for instance between:

Different versions of epics
Different number of channels
Different data lengths
Different numbers of clients and servers

At the moment I am thinking of running a test varying the following;

Number of clients 1->8
Number of servers 1->8
Data length 1->1KB per channel
Number of channels per server 1 -> 100'000
Client connections per server channel 1->8
get and put requests
3.13 and 3.14 clients
Redhat Linux 7.3 and 9.0 

All machines would be identical PCs running Linux, on an isolated network
(one machine will be configured with two network interfaces to give access
from the outside world). Servers would be 3.14. Network would be switched
100Mbit or Gbit Ethernet.

Any comments or suggestions?

Would anyone be interested in defining the tests that could be run and/or
participating in the testing (you would be able to login to the machines).
