Are the checkpoint images larger? (at least: is one of them noticeably larger?) That might account for the checkpoint performance difference. > Is there any parameter that can be tuned to improve the performance? My understanding is that there are some inherent bottlenecks in checkpoint / restart, such as the time required to dump out all the process images to disk. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
