Hello I'm working on solving an AFS issue that has been a problem at my employer before I arrived here. Performance in general has been poor, much slower than NFS. I ran bonnie++ to check this out and apparently read/write performance was not bad, it was file creation, deletion and renaming that took forever. Looking further this was do to the fact when transactions like this are done, it invalidates the cache, so the filesystem must be reread. When you are in a software development environment this is a problem. Engineers checking out an entire trunk to their AFS home would take FOREVER. So digging further it appears that code Has been added to improve performance. We are running an old version of AFS.. 1.4.1. Are there any configuration differences between 1.4.1 and 1.5.7?
Is there a FAQ posted regarding the upgrade? Can I have a mixed environment of versions? I'd like to update my replication servers first and run some tests Before I upgrade all the servers in the cell. Thanks.
