TortoiseSVN icon overlays and network shares/mounts

Question

Enabling TortoiseSVN icon overlays on network drives slows down the whole system.

What is the size of, and is there anything that can be done to mitigate this impact?

Answer 1

According to TSVN's lead developer Stefan Küng:

the drive type is checked last when the cache determines whether to show an overlay for a path. If the path is in the 'allowed paths' list, then the drive type isn't even checked so it should be faster. And of course the state of the checkbox shouldn't matter at all.
