It seems difference is an artifact of your file system (how much FS can keep in memory). I cannot reproduce the issue on my computer (2 minutes 25 seconds vs 2 minutes 15 seconds). For more accurate analysis, please provide snapshots in another format (for example in yjp format). Unfortunately npss+NetBeans are useless for analysis.
