Ubuntu Performance Question

[lada-h8kxHjy+vg4AvxtiuMwx3w at public.gmane.org]

I migrated my Subversion server from a 800Mhz Pentium 3 with 512 MB of
memory to a 3GHz Pentium 4 with 2 GB of memory. They both run Ubuntu 6.06
LTS Linux (2.6.15-26-386 kernel).
The P4 machine seems to be rather slow. Here is truncated output from top:

top - 15:19:19 up 5 days, 22:43,  1 user,  load average: 0.33, 0.09, 0.03
Tasks:  56 total,   1 running,  55 sleeping,   0 stopped,   0 zombie

And here from the P3 box:

top - 15:17:07 up 19 days,  5:09,  1 user,  load average: 0.00, 0.00, 0.00
Tasks:  51 total,   1 running,  50 sleeping,   0 stopped,   0 zombie

Swap:   979832k total,    18904k used,   960928k free,   262132k cached

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND       

 9848 lsvatos   16   0  2192 1076  856 R  0.3  0.2   0:00.16 top     

How is it possible for the same program to consume 10 times the CPU time?
I would appreciate any suggestions.
