Re: [Linux-cluster] GFS or Web Server Performance issues?

I think a part of the problem is perception. Clustering in most cases leads to _LOWER_ performance on I/O bound processes. If it's CPU bound, then sure, it'll help. But on I/O it'll likely do you harm. It's more about redundancy and graceful degradation than performance. There's no way of

Using a load balancer in front of GFS nodes is tricky. Make sure to set your scheduling rule (or whatever it is called in LVS) in such a way Do you mean such as a session, so that the user is not moved between servers? That's something I did take into account when building the LVS LB's. I also
