WinForm app speed issue

[John]

Hi

I have a multi-form winform database application. The client keeps
complaining that application runs too slow 50% of the time. The problem
seems to be in two areas;

a) app is slow maximising after a prolonged period of being minimised.

b) when user clicks on a toolbar to select one of the several already open
forms.

This seems to suggest that there is nothing wrong with application per se as
application works fine 50% and also maximising app or moving from one open
form to another open form does not do anything special code wise. Also as
other non .net apps run just fine on the same pcs, this can't be due to spec
of pcs. I have also ngen'd the app using command line 'ngen install
myapp.exe'.

I am therefore wondering what can be causing this slow response and would
appreciate any help in ironing out this speed issue.

Many Thanks

Regards

[John]

Maybe, your problem is the use of those 3rd party tools. Maybe, you should
be talking to Infragistics about speed issues using their controls.

Have you run a profiler tool to identify the areas that are causing your
slow down?
