I have no idea where the bottleneck could be. Two servers, a cable connecting eth1 to eth1, both are auto-negotiated at 1gbps on their own /30 subnet. The only thing there would be garbage NIC cards, possible, but not probable, or the cable, more likely, but I've never had an issue with it until now. Freshly constructed servers, too.<br>

<div><div><p class="MsoNormal"> <u></u><u></u></p><p>I was playing with the settings yesterday and it let me set it at 600M and it didn't make a difference in the sync speed at all. I then tried it with your suggestion, dropped it to 150M just to be safe. Still no difference. I wonder what the deal is. Could it be that this is the initial sync?<u></u><u></u></p>
