Basic TCP/IP Tuning

These are only some tips about the TCP/IP stack tuning suggested for Directory Server:

ndd -set /dev/tcp tcp_conn_req_max_q 1024
ndd -set /dev/tcp tcp_keepalive_interval 600000
ndd -set /dev/tcp tcp_ip_abort_cinterval 10000
ndd -set /dev/tcp tcp_ip_abort_interval 60000
ndd -set /dev/tcp tcp_strong_iss 2
ndd -set /dev/tcp tcp_smallest_anon_port 8192
ndd -set /dev/tcp tcp_naglim_def 1


In any case tuning is NEVER a one-shot. It's an iterative process in which you apply and measure the changes, possibly once per time.
