So I got my server in yesterday and have been tweaking and playing since then working on tests and configurations.
Real world I am getting about 200MB/s upload to the server and 300MB/s download from the server from RAM disk on client.
When I run iPerf in the standard configuration these are my results. (Running "iperf -sD" on server and "bin/iperf.exe -c 192.168.0.10 -P 1 -i 1 -p 5001 -f g -t 10" on the client)
[240] local 192.168.0.11 port 60552 connected with 192.168.0.10 port 5001
[ ID] Interval Transfer Bandwidth
[240] 0.0- 1.0 sec 0.18 GBytes 1.58 Gbits/sec
HOWEVER
When I run with a 512k TCP window size on the server I get full speed. (Running "iperf -sD -w 512k" on server and "bin/iperf.exe -c 192.168.0.10 -P 1 -i 1 -p 5001 -f g -t 10" on the client.
[244] local 192.168.0.11 port 60557 connected with 192.168.0.10 port 5001

[244] 0.0- 1.0 sec 1.15 GBytes 9.89 Gbits/sec
With this knowledge what tweaks do I need to make? I cannot seem to find how to change the TCP size on Freenas, or even if this is a good idea....
Thanks!!
