bspachman Posted July 29, 2004 Report Share Posted July 29, 2004 First, the obligatory system details & general speeds: Network: SMC Barricade Router w/3*10/100BT Ethernet ports + 802.11b Server-- Windows 2000 Professional SP4 Retrospect 6.5.350 10/100BT Ethernet NIC Backing up to 250GB SATA hard drive Local backups proceed at speeds of ~625 MB/min for the boot drive (IDE) to over 1800MB/min for the RAID subsystem on the machine. All great! Client1-- Windows 2000 Professional SP4 Retrospect Client 6.5.136 10/100BT Ethernet NIC This Windows client backup proceeds at speeds around 320MB/min. AFAIK, this is a normal, acceptable speed over a 100BT network. Client2-- Macintosh PowerBook G3 (Lombard) OSX 10.3.4 Retrospect Client 6.0.108 10/100BT Ethernet NIC Skyline 802.11b card This client backup is terrible. Generally speeds of around 2MB/min when connected with 100BT. The speed rockets up to 6MB/min when using the 802.11b card. I did a bunch of searching in the knowledge base and here in the forums and found this problem is not unheard of. The KB solution (using Terminal & ifconfig) doesn't work on my machine, but I remembered that the Network control panel under 10.3 allows you to set the speed & duplexing of an Ethernet connection. I tried setting the speed of the wired Ethernet to 10BT and the speed of the backup jumped up to 20MB/min for a little while & has now settled down to 2.7MB/min. What are my options? Does anyone have any ideas about solving this problem? Best, Brad Link to comment Share on other sites More sharing options...
waldorfm Posted August 10, 2004 Report Share Posted August 10, 2004 If the macs are connected to a switch make sure the switch ports are set to auto-negotiate, otherwise there will be lots of network communication errors on the switch port side.
