did you do testing at regular lan latencies? what i see on my networks is usually = 30µs. - erik I induced latencies similar to those found on the Internet. My tests at LAN speeds (500us in my sub-optimal setup) had 9P at essentially the same transfer rate as HTTP. My work was

issuing multiple outstanding messages is how protocols like aoe, pcie, etc. get speed. writes are posted. the question for me is how does one make this easy and natural. one way is to allow the mnt driver to issue multiple concurrent reads or writes for the same i/o. another would be to

Hello, I'm looking for advice on how to build a small network of two file servers. I'm hoping most servers to be Plan9, clients are Windows and Mac OS X. I have 2 houses separated by about 40ms of network latency. I want to set some servers in each location and have all data accessible from

Right now (only one location) I am using a Solaris server with ZFS that serves SMB and iSCSI. It works great, there's nothing wrong with it, but I would like a Plan9 solution. Or do you think iSCSI would perform better with this latency? (I can't use AoE as AoE is not routable). use a
