ParaSpd is a small utility which may be used to test the relative performance of different types of parallel ports on a given system.
How does it do this?
Paraspd contains typical examples of IO code as commonly used in parallel port peripherals such as network adapters, disks, tape drives, and so forth. Examples of 4BIT, 8BIT, and EPP/ECP IO code are included, which allows you to compare the performance of different types of parallel ports.
ParaSpd times the execution of the benchmark code samples as displays the results on one of three forms: Raw Data, Chart, Table.
ParaSpd includes a database of it's results when run on various other computers, which again allows you to compare your system and ports to results attainable in other configurations.
ParaSpd is a companion to Parallel, the Parallel Port Information System and many of the terms used in this document are described more completely in Parallel.Doc.
Note that ParaSpd does not identify your parallel ports... it simply reports the relative speeds of different types of ports that might be used on your PC. For example, ParaSpd produces EPP/ECP results even if you don't have an enhanced port.
So use Parallel to determine your PC's parallel port capabilities and configuration. This will help you understand and apply ParaSpd's results.
