Digging around in some links given by the Performance Team (which alludes that there are things you can do) I found:

Good luck!

The file cluster, unsurprisingly, is struggling. We are building a new environment where PSTs will not be stored on the network....in the meantime, is there anything I can do to let the existing file cluster stop struggling so much? I know that "don't store PSTs on the network" would be the ideal thing - but that's unlikely to change until we implement the new infrastructure in a few months. All of the usual performance monitor counters are showing low work items in the server service and the usual indicators of PSTs causing issues, so I'm pretty sure of the root cause of the file cluster performance issues.
