Hai, as compairison. Running Ubuntu 12.04 LTS. kernel 3.2.0-(latest ubuntu kernel ) Samba 3.6.12 Sernet release.
1 x ssd, top speed 400Mb/s ( reallife speeds ) 2 x 5400 RPM disk in raid 1, mdraid aka software raid. Draytek 2850 with gigabit ports. Copy speed from server to pc. about 110-120MB/s ( aka the speed i see in windows ) large files, like 2+ Gibabit files ) Copy speed from server to pc, about 40-80MB/s files from 1-50 Mb. Copy speed from server to pc, about 1-20MB/s lots of small files ( like 1kb-2Mb ) Tuning, windows side, Power schema, High performance disabled search indexing service. and . netsh interface tcp set global autotuning=disabled Tuning samba side. only, other settings are default. socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 SO_SNDBUF=131072 I suggest, upgrade your debian samba, to at lease 3.6.6 from backports. Or use the sernet packages. I noticed a improvement in speed after this upgrade. In my office i'm running samba 3.6.6 from backports on debian. On ubuntu im using the sernet packages 3.6.12 Good luck.
