Why do you assume the block is unnecessary? Unwanted, perhaps; but quite
necessary.

The best thing to do is find a faster disk for the log file -- or a
faster file system, so if you are Solaris, use ZFS.

If you have a good, fast database in your environment, you can set up
the log file to log into the database, which can be faster than a slow
internal disk. See
