Performance: PassMark PerformanceTest Suite
With PassMark PerformanceTest I can define the block size and send both fixed and variable sizes over the network connection. I’m using 16384 byte sized blocks for the fixed test and the variable test will run from 32-byte block sizes to 16384.
Fixed Block Size
To test the maximum throughput speed that a connection can handle, a fixed block size of 16384 Bytes is sent from the client to the server over a period of five minutes. The higher block size will allow the transfer rate to stay as high as possible – in the same way that large files transfer from one drive to another quicker than lots of small files of the same total size.
Variable Block Size
In a real world situation, the blocks of data that pass through a network adaptor are not of the same size each time, so to give a more realistic impression of how an adaptor performs, the adaptor is once again tested for a period of five minutes. This time however, the block size will vary from 32 Bytes up to 16384 Bytes in increasing steps of 148.7 Bytes each time.
