Synchronization performance in IDEA is abysmal but the official line seems to be: "Unfortunately there is nothing we can do to speed up IDEA working on network drives. Our official recommendation is to avoid them at all costs."
Many corporate environments dictate network drives. This is such a serious issue that JetBrains needs to fundamentally re-examine their approach on this issue. I'm contracting at a company where people are fee to use any IDE they want including having the company pay for IDEA. Well, guess what-- Eclipse performance is fantastic on exactly the same project. IDEA performance is so bad that even IDEA fans-- much less people willing to explore IDEA-- are against using running it. Having the project local isn't an option as the build and deployment both have UNIX dependencies.
Here is a typical issue file on this:
You will be getting new issues forever on this issue if you don't address it and you'll lose lots of IDEA sales and even lose some existing mindshare due to this problem.
Can you not come up with a faster alternative? A different way? Anything? Perhaps only immediately synch the files actually in the editor then do a low priority background thread synch on the rest?
I know JetBrains can solve this problem if they have the support of management and if they set their minds to it. This is a blocker of sales and erodes mindshare.
