Greetings, I have an odroidc2 board running kernel 3.14 with the following exportfs settings: /mnt/media 10.0.0.0/24(rw,no_subtree_check,nohide,insecure) the board has a 1000Gbit Ethernet, both ethtool and netcat based test shows 125 MB/s. I've tried to test the write speed of both nfsv4 and nfsv3 on the same file and I get the following results: dagg@NCC-5001-D /tmp $ ll /mnt/storage/video/Movies/tdm-stgc.mkv -rw-r--r-- 1 dagg users 4677381547 Apr 18 2013 /mnt/storage/video/Movies/tdm-stgc.mkv nfs V3 testing: dagg@NCC-5001-D /tmp $ time cp /mnt/storage/video/Movies/tdm-stgc.mkv /tmp/media/ real 13m38.090s user 0m0.007s sys 0m2.453s nfs V4 testing: dagg@NCC-5001-D /tmp $ time cp /mnt/storage/video/Movies/tdm-stgc.mkv /tmp/media/ real 16m32.828s user 0m0.007s sys 0m2.047s why is that? is my exportfs bad? can it be a kernel bug?
