Mon Nov 23 19:58:18 PST 2009 The goal was to write something that would outperform dd by sacrificing constant blocksizes, but that's proving elusive. However, it might be interesting to compare on multiple machines. On my 32 bit, dual core, 1.8GHz system running Ubuntu 9.10, I get close to dd's performance, but I wonder if I just happened to hit a good blocksize for this machine when using dd.
