Yes. I used ethereal to do the network trace and captured the entire
cycle of the commit. For 3.5 minutes, there were no network packets
transfer between the server and the client machine.

Unfortunately, at this rate it'll take 40+ days to complete the script.

Yup. That fixed it. I temporary paused the script and changed DB_CONFIG
the following parameters and ran svnadmin recover and now the commit is
happening every 2 second.

set_lk_max_locks 4000
set_lk_max_lockers 4000
set_lk_max_objects 4000
set_lg_bsize 1048576
set_lg_max 8388608

Thanks for your help!
