It's a very fast Raid 5, I don't think it's the disk because according
to performace tools its reading around 45% only. But there is just one
CPU used, you can see that because it is at 100%.
When loading a dump file into a clean repository one cannot run multiple
scripts, because data is references across the revisions. While dumping
I can do multiple scripts, I tried this with 8 scripts, so all 8 CPUs
were at 80%.

Subject: Re: Svnadmin dump/load on multiple processors
As someone pointed out some days ago, bottlenecks on svn performance may
come from disk, not from cpu.
Since you say you have fileS, perhaps you could create a script that
performs these processes in parallel. Still, depending on your machine
hw architecture this may not help (8 cpus using same disk controller?).
As to your question : I don't know about the dump file format, but from
its output I see when dumping / loading I guess it is something
sequential. If my assertion is true, few things could be done in
parallel.
