You can improve the speed of deployment by a) upgrading to version 3 b) disabling virus scanners c) buying an SSD
In addition to Arjan: d) Add some internal memory to the client PC. e) Reduce the number of events/startup microflows. f) Keep your model as clean as possible. g) Keep an eye on size of the client PC dev deployment folder (in our case it is not cleaned automatically), if it gets a large volume, clean it.
BTW: disabling virus killer hardly made any difference in our case. also changing JVM settings did not create a major improvement.
