quick look into sysinternals filemon log for IDEA #1185
startup shows that quite some seconds are spent while
bytewise (1byte) reading of resources.jar - just FYI
this reminds me of old annoyance: IDEA insists on reading
from slow network drives - which is the reason why some
people in a company I work for do hate to use IDEA.
Note that the slow network drives need NOT be in any way
part of an IDEA project to cause the slowdown.
