Howdy folks...

First off, I've written multi-threaded apps using Posix-Threads before, so I'm not a complete threading n00b

Anyway, I'm updating my old MC XML Export plugin, which is single-threaded and uses yukky hacks to make it look multi-threaded However, I want this new version to use a separate threads so I can remove the GUI from the back end and have things like status-bars and cancel buttons and all that nice fluff.

I'm using C# .NET and I'm finding that when I put my export code into a separate thread (using System.Threading) it runs about 10x slower than running it in the same thread as the GUI, which is obviously quite a pain.

I was wondering if anyone's had any experience with threading in .NET and knows why this is happening.

Basically it goes like this:

ex = new Exporter(blahblah);
ts = new System.Threading.ThreadStart(ex.doExport);
t = new System.Threading.Thread(ts);
t.start();

Nothing wrong with that, right? However, the doExport method takes about ten times longer when doing it that way than when just going:

ex = new Exporter(blahblah)
ex.doExport()

However that leaves me with a completely un-usable GUI, which is dumb.

Any ideas?

Thanks,

Scott.
