What Linux distributions did you try?

What hardware were you using?

What kind of troubleshooting did you perform?

>> Six weeks in, things changed. The Linux installations started to degrade — subtle at first, then undeniable. Random slowdowns. Browser links that wouldn't register for 10 or 15 seconds. The kind of frustration that makes you stare at the screen and wonder what's happening under the hood. It was consistent across distributions, which suggests this wasn't just a bad package here or there. Something fundamental was happening.

Without more details it would be difficult to determine what problems you were having.

I have never had problems like you describe with Linux. I would be interested to know more details.
