Hi,
I had the same problem. On December 09, 2011, 05:50:08 PM someone asked approximately the same question ("Arduino 0022 and 1.0 super slow").
The answer down at the bottom worked for me.

the answer ist "rxtxSerial.dll"
I'm change to version 2009/03/17 (97kb) and 0022, 0023 and 1.0 starts fast and no problems with Menu Tools.
