In ISS you can also adjust some settings, like the number off Worker threads or the amount of
memory per worker thread on the CloudBackupService Application pool.
You can find these settings by entering the Internet Information Service (IIS) manager, click on
the Application Pools settings and right click on the CloudBackupService application pool to
select the advanced settings. Here you will find the above settings.
For instance you can change the maximum work processes to 4 instead of 8, this all depends
on the number of servers you have running and of course the number of connections per
server.
Rules for the worker processes:
Connection handling per CPU:
General rule of thumb for connection handling can be applied:
Every cpu core has 8 worker processes (= w3wp.exe) running
1 worker process can handle 30 active connections (an active connection is a client that is
performing a backup or a restore)
1 worker process is used by the Managementconsole itself
Example:
one 3 Ghz DualCore has: 2 cores = 2 x 8 = 16 workerprocesses - 1 (for the managementconsole)
x 30 connections = 450 active connections
Please note that the cpu will then be 100% used.
