performance?

performance?

[PERELYUBSKIY, DENIS]

hello,

i am generally very happy with source navigator,
but it is very slow when x-ref'ing fairly
large code trees ( several hundred thousands lines )

i was just wondering if there were any plans
to improve performance, or is it just the nature
of the beast: it would take too long, and not
be worth it at the end? 

also, i'd like to comment on one of the earlier
threads which i saw in the archive:

"SourceNav with Windows 2K problems".

i too, see this problem, where the mouse cursor 
must be inside the window for the status bar to be
updated, and processing to go on.

please dont get me wrong, i love the program though.
once its done parsing, it is very, very usefull

thank you very much.

Umm.. several hundred thousand lines is quite a bit to x-ref if you
think about it.  One way of looking at it is to see how long it takes to
compile that much code with optimization turned off - it is a similar
exercise.

You also may want to check that you don't have cross references to local
variables turned on, this takes a _lot_ more time.

In general, X-Ref is O[n^2] where n is the number of variables in your
source code. So large amounts of code produces a non-linear increase in
the time it takes to X-Ref.
