[lvs-users] Are LVS / ldirectord Multithreaded?

[Graeme Fowler]

Not being entirely au fait with ldirectord, I had a read of the source
code this morning and found the following which might (or might not)
help you out:

fork = yes│no

If yes, then ldirectord will spawn a child proccess for every virtual
server, and run checks against the real servers from them.  This will
increase response times to changes in real server status in configura-
tions with many virtual servers.  This may also use less memory then
running many seperate instances of ldirectord.  Child processes will be
automaticly restarted if they die.

Default: no


I was going to suggest modifying ldirectord to fork health check
processes out for each VS, but Horms (or maybe Jacob) already did it :)

That should help. You'll end up with a lot of processes running but they
should be able to deal with the shorter check interval far better than
screaming through hundreds of checks every two seconds.
