Shrinking db4 log file size

Should we reduce the default log file size from 10 Mbytes to something
like 1 Mbyte? This will reduce the disk storage requirements for sites
running hot-backup.py pretty significantly I would think. Right now
each running of hot-backup.py will backup at least one 10 Mbyte file.
Reading

    http://www.sleepycat.com/docs/ref/log/limits.html

shows that its unlikely that we'll run out of log files.

Also, do people have any comments on increasing the in-memory log buffer
from 32 Kbytes to 128 Kbytes?

Here's what I've placed in my DB_CONFIG:

### Log file subsystem
#
# Read the documentation at
#
# http://www.sleepycat.com/docs/api_c/env_set_lg_bsize.html
# http://www.sleepycat.com/docs/api_c/env_set_lg_max.html
# http://www.sleepycat.com/docs/ref/log/limits.html
#
# Increase the size of the in-memory log buffer from the default of 32
# Kbytes to 128 Kbytes. Decrease the log file size from 10 Mbytes to
# 1 Mbyte. This will help reduce the amount of disk space required
# for hot backups. The size of the log file must be at least four
# times the size of the the in-memory log buffer.
set_lg_bsize 131072
set_lg_max 1048576

Best,
Blair
