- Hi, Not really an Amanda question but I'll try anyway... I can't get better than ~60MiBs to LTO4 tape when using amtapetype. I tried 32k 1024k and 2048k, with and without hw compression enabled. Any

- 60 MiB/s is certainly capable of hitting a number of hardware bottlenecks - RAM, SCSI, PCI bus, even CPU when generating random data. You may want to try a simpler test with just 'dd' from e.g, /dev/

- * Dustin J. Mitchell <dustin AT zmanda DOT com> [20090612 11:47]: I have a exact clone of that library with same LTO4 drives and I can routinely achieve ~100MiBs on that server. This server is newer
