I don't know of a specific reason that close session should be slower
from another machine, i.e. I don't think you're doing anything wrong.

Can you maybe run the Test with either:

  java -agentlib:hprof=cpu=times Test

or 

  java -Xprof Test

(or both) and send the results? Also, how many projects are we talking
