Run a relay against a buildroot optimized LINUX powered with PBIOS to shave several seconds....

The green bars are for PDOS and the red bars for LINUX. The slowest uses the maximum 80 character width and the fastest scales to a percentage of that width. The bars thus visualise the difference in performance.

The "slow" block output in PDOS (1.63s) compared to LINUX (0.75s) is due to the fact that LINUX don't actually write the data to disk. The data will be stored in the disk cache to be written out to the disk much later. PDOS also writes the data to the disk cache, but by the time the file is closed all the data are also permanently in the disk. This is the default behaviour of PDOS, but it can also be bypassed intentionally for applications that requires it.

Above is the relay in video.
