Happens all the time. My PC is high spec so not the issue. 7.3.x has been unusable for me.
Comment 3 Jaroslav Havlin 2013-07-09 07:10:50 UTC 
The slowness is caused by class loading, it cannot be fixed in NetBeans, I'm sorry.

On Windows, it can happen quite easily if the hard drive is under heavy load, even on high spec PCs.
But it is still quite strange that it happens all the time. Can you please attach another profiler snapshot if it happens again? We should ensure that the cause is always the same.

Thanks for reporting.

I have an SSD, so its IO speed is not exactly a problem either.

I've checked the snapshot again, and the only operations that takes some time are class loading and initialization of the dialog, no unnecessary I/O is invoked by NetBeans.
Maybe the SSD drive is fast, but the Windows filesystem might be slow for some reason.
