Brian, My personal opinion is:
ldirectord uses LVS as the backend which is blindingly fast and layer 4 only. The health checking part is not parallel so for large numbers of real servers can become slow. I've been trying to get someone to re-code the check as a child process without any luck so far. On modern CPUs performance is less of an issue than it used to be and HaProxy scales very, very well. 2009/5/14 Brian Kruger <[email protected]> > > Hi, > > I've been looking for a nice load balancing solution.
