I apologize that this question is not directly related to mdadm, but I thought some of the list might have experience in a mixed Linux/Windows environment. I am running a mdadm RAID5 file server on a Ubuntu 8.04 Linux box on a gigabit LAN. I am using a Highpoint 2680 card at PCI-E 4x as the controller (I have also tried the motherboard SATA connectors directly). I am running SAMBA on this box to share my RAID5 with my main Windows PC running Windows 7 64 bit (although I have gotten similar results with Vista also). My question is related to what I consider slow speeds when reading from or writing to the array from my Windows box. I get anywhere from 20-30MB/s in either direction when transferring a single large file (3 GB as an example). I haven't done detailed benchmarking on the array, but spotchecks of file transfers from another drive on the same linux box are giving me speeds above 100MB/s for reads and writes. Does anyone have any suggestions for improving my speeds across the network? I don't know if SAMBA is causing some kind of bottleneck or if Windows is not playing nice or if it's something with my network configuration, but I was hoping to get alot closer to saturating the gigabit connection. Any help would be greatly appreciated. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
