It has OK performance. I am currently using it in a > RAID0+1 type config. Where can I learn more about the pitfalls? I have a model 466 waiting to get employed (RAID5 config with three IBM drives) and get very poor throughput in the 3MB/s range. I'm aware of the expensive directory manipulations but even "dd if=/dev/zero of=$FILE bs=8388608 count=..." is this slow and I don't know where to start searching. This has been with 4.0-R and 4.1-R, cvsup to -STABLE has just finished and results will be available soon. Is there a checklist for the things to do / to make sure? Could it be bad cabling rather than a software configuration thing? virtually yours 82D1 9B9C 01DC 4FB4 D7B4 61BE 3F49 4F77 72DE DA76 Gerhard Sittig true | mail -s "get gpg key" Gerhard.Sittig@gmx.net -- If you don't understand or are scared by any of the above ask your parents or an adult to help you.
