Really? My experience is that the speed of /dev/random and /dev/urandom in FreeBSD is far from to be sufficient for LTO3. # dd if=/dev/random of=/dev/null bs=64k count=10000 10000+0 records in 10000+0 records out 655360000 bytes transferred in 20.414294 secs (32102996 bytes/sec) # dd if=/dev/urandom of=/dev/null bs=64k count=10000 10000+0 records in 10000+0 records out 655360000 bytes transferred in 20.418363 secs (32096599 bytes/sec) Processor: CPU: Genuine Intel(R) CPU 3.20GHz (2793.02-MHz 686-class CPU). -- Rudolf Cejka <cejkar at fit.vutbr.cz> http://www.fit.vutbr.cz/~cejkar Brno University of Technology, Faculty of Information Technology Bozetechova 2, 612 66 Brno, Czech Republic ------------------------------------------------------------------------- Using Tomcat but need to do more?
