local weather conditions? i get a much tighter grouping and fcp is faster than http: minooka; time cp /n/sources/extra/plan9.tar.bz2 /dev/null 0.00u 0.18s 343.83r cp /n/sources/extra/plan9.tar.bz2 /dev/null minooka; time fcp /n/sources/extra/plan9.tar.bz2 /dev/null 0.00u 0.20s 54.64r fcp /n/sources/extra/plan9.tar.bz2 /dev/null minooka; time hget http://plan9.bell-labs.com/sources/extra/plan9.tar.bz2 >/dev/null 0.20u 0.20s 55.05r hget http://plan9.bell-labs.com/sources/extra/plan9.tar.bz2 and for good measure: minooka; time hget http://plan9.bell-labs.com/sources/extra/plan9.tar.bz2 > /n/other/quanstro/plan9.tar.bz2 0.17u 0.89s 55.37r hget http://plan9.bell-labs.com/sources/extra/plan9.tar.bz2 if i do a different test where the remote as 1mb of bandwidth (43ms ping): ladd; time cp /n/t1/n/other/quanstro/plan9.tar.bz2 /dev/null 0.00u 0.19s 302.93r cp /n/t1/n/other/quanstro/plan9.tar.bz2 /dev/null ladd; time fcp /n/t1/n/other/quanstro/plan9.tar.bz2 /dev/null 0.00u 0.25s 179.87r fcp /n/t1/n/other/quanstro/plan9.tar.bz2 /dev/null ladd; time hget http://t1.example.com/files/extra/plan9.tar.bz2 > /dev/null 0.20u 0.24s 175.94r hget http://t1.example.com/files/extra/plan9.tar.bz2 the original test i did was looked funny because i'd used ssl for the import but regular http. so the system time was skewed i wonder if some of the really bad 9p performance could be related to aan. - erik
