Baseline Throughput

Throughput for single-stream, using nuttcp. Hosts may not be storage resources, but machines w/ similar connections as mcat/storage nodes.

Untuned transmit/receive numbers in mbits/s. Raw Data

SRB Speed Tests

Speed tests were performed using three samples, 1000 x 1k files, 300 x 10m files, and 100 x 100m files. Tests were run starting w/ 5 threads and continuing until total plateaued and per-file time started increading. After this point, a bottleneck was reached, either mcat/srb or network limit.

  • Total - Total time in ms for transfer, from directory listing to last thread exiting
  • avg - Average per-file time (ms)
  • throughput - Aggregate throughput size / time.

1k test

1000 files in 10 directories, each directory contains 100 1-k zero-filled files.

Through 25 threads load average on umiacs mcat was negligable

  • erasrb02 is only on a 100mbit link, so 10MB shows saturation. Further testing showed saturation was achieved w/ only 2-3 threads.
