Description
presales customer is connecting 1.1dp java client to dp4 and seeing 160% cpu load.
With the older client jars against dp3 they were seeing 100-120% cpu load.
This cpu load is right after application start with no load at all, after connecting to couchbase.
from customer:
"This issue specifically in DP3: http://www.couchbase.com/forums/thread/high-cpu-load-even-when-java-database-client-idle We've been seeing this both on mac and ubuntu."
