Spark slugish when compression is enabled

OS: XP sp2

CPU: 1.5ghz

Mem: 2.0GB

IM Client(s): Spark 2.0.8 and 2.5 beta 4 (using the clients that don’'t include java)

Java version “1.6.0”

Java™ SE Runtime Environment (build 1.6.0-b105)

For some reason when compression is enabled Spark is very slugish or sometimes freezes where I have to kill the process.

Has anyone else ran into this issue?

Anyone?
