WHAT IS THRUPUT?
ThruPut is a DOS disk benchmark utility written after I tried conventional
benchmarks on an EISA SCSI-2 NetWare server I had just prepared and found that
most of them blew up and others gave figures that were obviously far too slow.
ThruPut gives real figures. That is, it uses normal DOS calls to move its
data, so the number you're getting is an indication of how fast DOS can
transfer data to and from the drive being tested. This differs from low-level
benchmarks like HDTEST, which give pie-in-the-sky figures based on theoretical
maximum capability of the hardware, and from high level benchmarks like Norton
System Index, which gives an index that is useful only for comparing two
systems, and not for understanding what your system can do.
Even though it was designed to handle very fast systems, ThruPut does not
take forever on slow systems. This is because ThruPut was also designed to
benchmark floppy drives and networks. It accomplishes this by performing a
brief benchmark using an inefficient loop that estimates how fast the system
is, and then performs a longer test using a more efficient loop to give the
best possible results. So, whether you're testing an XT's floppy drive or the
latest technology in striped disk arrays, ThruPut is for you.
QUESTIONS AND ANSWERS:
Q: Which LANs will work with ThruPut?
A: In theory, all of them. ThruPut uses only basic DOS calls, and any LAN
that doesn't support them is a pretty poor excuse for a LAN. You will,
however, need to have create, write, read, and delete access to the
directory in which you wish to run ThruPut.
Q: Will ThruPut work with CD-ROMs?
A: No, because they are read-only.
Q: Will ThruPut work with WORM drives?
A: Yes, but since you can't recover space used by deleted files on a WORM
drive, allowing ThruPut to chew up unrecoverable space is not a good idea.
