[Samba] performance regression between 30.14a and 3.0.20
Hi, Suddenly occurred to me that I wasn't seeing the performance I used to while running 3.0.21c. Went back and tested 3.0.14a on the exact same configuration and boom, smaller writes (8K) were about twice as fast. I narrowed it down to a change between 14a and 20 but there were alot of changes in there. Can anyone think of what this could be? Thanks, Greg -- Greg Dickie just a guy Maximum Throughput

If you can give me the exact same test config I can run under cachegrind and it'll tell me exactly where the extra time is being spent between the 3.0.14a and 3.0.20 versions. Thanks, Jeremy.
