- e12e 12y agoIf I'm reading the numbers right[1], and converting correctly, infiniband is on the order of 5000 - 500 ns. I didn't mean to imply that the network isn't slower, just that it's possible to do quite a lot better than gigabit ethernet quite cheaply.

- vardump 12y agoYup. Infiniband + RDMA is pretty cool, but RDMA is also rather scary. I mean, writing remotely to another systems (physical) memory. In the same time I do wonder why this is not being used more nowadays.
