I have a Linux Server (3.06 Xeon) with a very fast RAID array -- reads at around 500 MB/sec as clocked by Bonnie++. I have 6 GigE nics on my machine -- on two 133Mhz PCI-x bus segments (not on the same bus as the RAID drives)
I have noticed two puzzling things and I'm wondering if anybody has any ideas about why I'm seeing these: 1) transfer speeds over a single NIC from a single Windows XP workstation to the Server (host to host, no switch in between) starts out at around 43 MB/sec but then drops off to around 30 MB/sec. I don't think it's a disk speed issue on the Windows side, because data is coming from an 8 disk RAID-5 on the Windows side. 2) transfer speed from the Server to 3 windows workstations seems to max out at around 60 MB/sec total. One windows workstation can get around 40-45 MB/sec, but if I try to achieve maximum transfer speed with to 3 Windows machines each only gets about 20 MB/sec. Again, I don't think it's a disk speed thing on the Linux side -- and on the Windows side the data is not being stored on disk but rather it's being played out as video. So, the question is, does Samba have any configuration options that might limit the total throughput to the Network? And if it's not Samba that's causing the bottleneck, does anyone have any other ideas. Thanks in advance.
