Hello, Another French student in the rsync mailing list. I have been working on rsync this year for a documentation project for school and I would like to give some comment about rsync block size optimization first, and then to submit a way to make rsync choose by itself the optimal blocksize

I believe that the compression option turns on compression of transfered data, including file lists, instruction streams etc. Even with compression turned off, the miss data in the delta is still compressed. nope! Compression only compresses file data, not file lists etc. The file lists are

optimization for rsync

2001-10-03 Thread Jason Helfman
What flags or options could be used to optimize rsync? I have seen a huge amount of cpu and memory be used in this process we have. I think using the --delete function is a lot of overhead. The options we normally use are -avrpg I would like to reduce all unnecessary processing and overhead.
