exabyte record size limit

[Jeremy Webber]

Hi all,

FYI, I did some performance tests on an Exabyte connected to a Sun 4/280 some
years ago, and found that transfer rate was maximized for transfers of 64K.
That is, transfers below that block size were substantially slower, and
transfers above that block size showed no noticable gain.

Very small transfers also seemed to use more *tape* than larger transfers.  I'm
not sure why.  1K blocks got less than half the storage on the tape that 64K
blocks did.

All block sizes were multiples of 1K.
