How are you checking whether a file exists or not? do you use ls? Can you make sure, that ls doesn't send a stat call on each of the files in the directory (as in ls -l )? if ls just sends readdir calls and still the performance is low, let us know about it. If you need stat calls, you might need stat-prefetch, which is currently not funcitonal. > > I've got an AFR configuration. > > so, when someone uploads 10 files, it checks for the file existing, > which does a directory scan which causes afr to check the other > server, however this takes a reallllly long time. > and it does this for each file, which is a problem. > > which performance translator would help the most with this. > > the AFR configuration uses local read-volume. > > will any performance translators help given it's an AFR config?
