Storing your workspace on a network drive or even a local USB key drive can really mess up performance because of the level of read/write cycles that the platform makes to the metadata folder and caches. It’s generally not a good idea.
I’ve even seen it perform subpar on a gigabit ethernet network. Not too much you can do, the IDE just does a ton of disk access, so offloading that workspace is going to incur that penalty of increasing the latency of every single read and write by a factor of 10 or 100 on slower networks.
