On the new computer, re0, and I see zero errors and 70K packets in/out. On the server, re0, no errors and about 65K packets in/out. Neither computer shows tcp drops due to checksums (literarlly 0). I did not try this build with the new computer under 9. It occurred to me that I need to find a parallel filesystem exerciser and try that, as simpler than the thunderbird build process.
