Performance issue

Hello,

I am working on a small video server.

I'm using a large scsi disk. The first part of the disk is raw used for large
video chunks and on the second part of the disk is an ext2 filesystem. On this
filesystem data is stored for the database.

Now I am trying to play 2 videostreams from the first part with a bitrate of
about 0.8 MByte/s using generic scsi commands. This works fine. But when I also
start a process that copies data to the database partition then the 2 videostreams
collapse. I tried different priorities and also played around with different
schedulers. I also lower down the priority of update (bdflush). But this doesn't
help anything. I'm using kernel 2.0.34.

Anybody an idea how to solve this problem?

Thanks,

Erik.
