Arduino in Windows 8

Arduino software is slow in windows 8 whyy..........i update all drivers......

Maybe because Win8 is a POS?

More seriously, which version of java are you running? Sometimes the latest JVM isn't going to get you the best performance, in fact, I often find it quite the opposite. I'm still running an older version of Java on my Win8 workstation because newer versions mess with an application that I need.

What are your computers specs
