Performance Improvements since 1.2.10

I ran some rough performance tests between 1.2.10 and 1.3.73 on
argos.mit.edu.  argos is a dual opteron64 box with 2gb ram; 100MHz
networking; and fast scsi drives.  The cell used was athena.mit.edu.

The system was configured to use a 200MB cache and no MTU constraints.
The test is a simple one involving copies of a 170MB file to and from
the cell with a "fs flush" command executed before each operation.

The resulting numbers are really rough but they do provide a good
indication of the performance improvements which have been acheived
in the last year.

                  1.2.10          1.3.73       improvement
               ------------    ------------    -----------
write/crypt   1.836 MB/sec    2.793 MB/sec       52.1%
read/crypt    1.497 MB/sec    2.897 MB/sec       93.5%

write/clear   2.927 MB/sec    7.123 MB/sec      143.4%
read/clear    2.065 MB/sec    5.991 MB/sec      190.1%
