Hi all,
I ran into a weird problem with the Solaris 10 nfs server. Here is what happens every time:
If I transfer a larger file to the Solaris 10 box via nfs, the speed starts dropping after around 1 gigabyte has been transferred. It keeps dropping and after approx. 2.5GB have been sent, the speed has gone down to about 50%. If the file is larger than that, the speed keeps dropping even more.
The network of the server is fine. Tests with iperf show splendid results and transferring the same file to the same folder via ftp works fine as well. So apparently the problem is nfs specific.
The client is osx and has no such problems with other nfs servers running a different os.
The Solaris 10 in question is running in 32bit mode on x86 and the filesystems are ufs. It has the following network related settings:
tcp_conn_req_max_q 4096
tcp_conn_req_max_q0 8192
tcp_max_buf 3145728
tcp_recv_hiwat 1048576
tcp_xmit_hiwat 1048576
udp_recv_hiwat 1048576
udp_xmit_hiwat 1048576
Any clues would be welcome!
