An easy way to find about a /dev/null congestion could be to measure its throughput every now and then. Mine doesn't seem too bad, it shuffles 33 MB/s: j@uriah 397% dd if=/dev/zero of=/dev/null bs=1m count=100 100+0 records in 100+0 records out 104857600 bytes transferred in 3 secs (34952533 bytes/sec) Does anybody know what happens to the data bits crap inside /dev/null? Are they simply burnt? Or are they melted down and converted to null bytes for /dev/zero? -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
