dovecot and nfs readdir vs readdirplus operations
...rs (about 25%) directed to the
new farm, performance is very poor, even useless.
Looking for NFS problems, we have found a lot of differences in nfs
operations. For example, this is the nfsstat of one of a new servers at

Do you have jumbo frames (if yes, you should have them on clients and server)? You might think abo...
