I posted previously about slow rdump times from linux to solaris. I later tried dumping a local partition to another partition on the same linux box, and it was blazing fast with no errors. So then I just tried sending packets from linux to (a pipe to rsh to) solaris and timing it. In this environment, linux is butt-slow when compared to other unices. All machines are on the same 10base-t network. Check it out:
linux->solaris time dd if=/dev/zero count=16384 ibs=1k | rsh ale dd of=/dev/null obs=1k 16384+0 records in 32768+0 records out 24459+10016 records in 16384+0 records out real 1m27.993s user 0m0.290s sys 0m0.790s solaris->solaris (two different boxes): time dd if=/dev/zero count=16384 ibs=1k | rsh ale dd of=/dev/null obs=1k 16384+0 records in 32768+0 records out 32768+0 records in 16384+0 records out real 0m17.389s user 0m1.814s sys 0m6.696s aix->solaris # time dd if=/dev/zero count=16384 bs=1k | ( rsh ale 'dd of=/dev/null bs=1k' ) 16384+0 records in. 16384+0 records out. 11491+11492 records in 11491+11492 records out real 0m15.27s user 0m0.12s sys 0m1.27s Any ideas as to why rsh/rdump are so slow? If I rcp files from this linux box to that solaris box it's quite fast, same with ftp. morgan P.S. Would have tried the same thing with hpux, but no /dev/zero. -- VVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVV >> M o r g a n F l e t c h e r http://www.hahaha.org << >> Tibi gratias agimus quod nihil fumas.
