running threads

Hi

I'm writing an application which basically takes images from pixelink
camera and does some calculations on them.

I need to monitor the status of the system for 2 things: presence of
camera and connection to SQL server.

I also have a preview feature.

Right now it's all being done by a two timers (one for preview and
second for status) which run threads for status/preview.

On a decent Core 2 duo everything is quite smooth but on single core CPU
responsiveness of the application is not so good (sometimes main form is
frozen for couple of seconds).

How should i do those 2 processes so that they don't have an impact on
application performance?

Thx for any info!

What type of Timer are you using? If it's Windows.Forms.Timer you're not
using a background thread.

Maybe you can provide some detailed code of what you're doing in your
Tick/Elapsed event handlers?

In the timer i'm running a thread

---
Thread Status = new Thread(statusJob);
Status.Start():
----

It's hard to say what the problem could be with such little to go on.

I agree with Peter though, spawning an new thread on ever Timer tick isn't
the most efficient method.

So what method would you suggest for this purpose?
