Also make sure you've disabled the reverse dns lookups for the log entries; those generally add _horrible_ latency to connections, and logging the IP address is all you actually _need_. Back in 2001, on a 200 mhz pentium III, I was getting 3.2 connections/second, and around 300k/second throughput. (That wasn't with dropbear, but that was a performance ballpark for comparison.) If your microblaze really is taking 12 seconds to connect, you should profile this and see what's going on. Is the CPU really busy the whole time? Rob
