After a comprehensive study of Diver using different versions of itself, Windows, Java and Eclipse, it has become apparent that there are general stability and performance issues for Diver on Windows 7 (and probably Windows Vista). Windows XP remains unaffected and Windows 8 has not been tested. The problem results in traces taking an extremely long time to be stored, applications lagging while being traced and traces failing to store. We believe this to be an issue regarding Windows 7 and Java and how threading and /or memory management is handled. This might require an overhaul of the Diver data layer and may not be fixed in the near future. Please continue to post issues on Github and we will try to help where ever possible.
