git-fast-import works great. I parsed and built my pack file in 1:45hr. That's way better than 24hr. I am still IO bound but that seems to be an issue with not being able to read ahead 150K small files. CPU utilization averages about 50%. I didn't bother reading the sha ids back from fast-import, instead I computed them in the python code. Python has a C library function for sha1. That decouple the processes from each other. They would run in parallel on SMP. My pack file is 980MB compared to 680MB from other attempts. I am still missing entries for the trees and commits. -- Jon Smirl jonsmirl@xxxxxxxxx - : send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
