I mount the share as a smbfs share and copy the files(120MB average realmedia files) from linux to windows share cp *.rm /mnt/desktop I look at iftop.. I see 3 figures.. 43.9Mb 46.2Mb 26.4Mb (I take it that translate to 1bit=8bytes, 43.9Mbs/8=5.5MB/s??) Using Gkrellm I see transmit = 6.1M SO.. I'm at a loss. What's the best method for measuring throughput? I'm gonna try out the ttcp util mentioned by dalen. (but Until now, I've not received a email response from them!!) so... I'm at a loss.
