HA Proxy balanced by server loads...
Can I make a configuration that pfSense checks the load of servers and send more packets to the server with less load?
Thanks in advanced.
To query the servers in order to determine the load? Not by default. Might be scriptable but I've never seen it done.
There are various load-balance algorithms though for determining server load by throughput or connections etc:
I need to configure high availability for SMTP, my idea is distribute connections based in the load of servers.
For example, when my first server is proccessing mails with large attachemnts, the second server will receive more connections during the time that first server has a high load of proccess.
Hmm, not sure I've seen that specific use case but I would set it up and try the different algorithms to see what works best for you.
