Its locking model is incredibly slow (500 locks/second on a filesystem mounted with quotas enabled and noatime) an...

Hello everyone, I am currently running Dovecot as a high performance solution to a particular kind of problem. My userbase is small, but it murders email servers. The volume is moderate, but message retention requirements are stringent, to put it nicely. Many users receive a high volume of email traffic, but want to keep every message, and *search* them. This produces mail accounts up to

...formance by adding more disks on the fly. (IBM uses GPFS to create scale-out NAS solutions http://www-03.ibm.com/systems/storage/network/sonas/ , which highlights a few of the features available with GPFS) There's no problem running GPFS on other vendors disk systems. I've used Nexsan SATAboy earlier, for a HPC cluster. One can easily move from one disksystem to another without downtime. Cons: It has it's own page cache, staticly configured. So you don't get the "all available memory used for page caching" behaviour as you normally do on linux. There is a kernel...
