The figure above comparing Linux and PDOS overhead on disk access is based on data from real life.
We have measured 3 times faster file I/O disk transfers on PDOS than Linux.
We have measured a transfer rate of 191 MB/s on PDOS using the same hardware as in the relay between PDOS and Linux.
The figure is based on the assumption that the SATA II interface delivers 3 Gb/s (375 MB/s). For lower hardware transfer rates, Linux performance will be worse if you care to do the math.
As PDOS is 3737 % faster than Linux (or more), you can reduce hardware cost dramatically and still do the job using PDOS. The functionality of the run time library is enough for most tasks and GNU software will run on PDOS too (but faster).
