I'd be surprised if that U5 was faster than the 1GHz x86. Back with OpenBSD 3.7 or so, I found with Ultra 5's that those which had the lower sized L2 cache, were a lot slower than those with the 2MB L2 cache. Direct crossover connection: 94.1 Mbits/sec (end-point directly to end-point). 360MHz in the Ultra 5 (256k L2): pf OFF: 67.2 Mbits/sec pf ON: 47.3 Mbits/sec. 333MHz in the Ultra 5 (2M L2): pf OFF: 77.0 Mbits/sec pf ON: 74.0 Mbits/sec. The 270MHz UltraSPARC in your Ultra 5 probably has 256k of L2 cache, so I think you'll get a speed penalty due to cycle speed and the small L2 cache size. Although lots of pf performance gains have been made since then and I don't know if any of them would have made the L2 difference less dramatic. Shane
