were some functionality added, maybe it affected
performance.
This doesn't match my experience.
Exactly which navigation feature are we talking about? I've been
noticing pauses sometimes when opening files, saving files and when
doing other actions. But those pauses are fairly short so I can't
capture a thread dump. I think it might be garbage collection
running. I use -Xmx1000m in my eclipse.ini which should be plenty
but I see the heap status grow and shrink very often. I've been
thinking that it might be the computation of the active AST that
allocates a lot of memory. This is with a fairly recent build of
8.1.0. I'll try to use -verbose:gc to figure out if GC is taking a
lot of time.
The standard way of troubleshooting slowness is to capture
Eclipse thread dump during an unusually long delay.
Yevgeny, perhaps you could also check for GC performance? In
eclipse.ini, add -consoleLog before -vmargs and -verbose:gc after
-vmargs
It
would be great if someone could refer to my
questions/comments from original mail
Thanks
a lot,
Yevgeny

Is there anything that
prevents you from using a more recent version of
CDT?
For
some reason when one of the above files is
opened (for the first time) it could take
about 30 seconds till outline with one
line is shown. I was wandering what does
it do during this time? I would guess that
parsing file with one include line should
not take that long. The second time is
much faster because of the cache.
BTW:
Eclipse workspace and project reside on
local file system. If opened "h" file
resides on local file system or NFS, will
it affect the time till "outline" has
finished showing its elements? I am asking
because above header files reside on NFS.
From my testing I did not see any
performance differences.
