Dear list, on the German user list, there has been a thorough discussion about performance optimization of NFS. Accordingly, udp (set by default) connections are slow due repeated loss of data. Therefor it was highly recommended to switch to TCP mode. Maybe this is worth a wishlist entry? /etc/auto.master => append ",tcp" to your option list otherwise, mount NFS shares with option "-o tcp". Did anybody else try this? Regards Ralf
