AmigaOS4 Feature Set: Release 1

Is The Exec NG fast compared to Windows and Linux

In a word:  No

In two words:  Not even close

In Three:  Doesn't even compare.

ExecNG had context switching times posted (context-switching being a key for any microkernel OS).  I took those (1ms for a simple switch, 4ns for round-trip) and compared.

LinuxPPC 2.4.18, unoptimized, had such times of 0.8 and 2.6.  Optimized, using a rtKernel, they got 0.6 and 1.8, respectively.  

Windows NT 4.0 PPC-version, had a time of 0.85 and 3.1ms, respectively.  

Now, I don't have MorphOS's times, but when I do I'll be glad to post them here for comparison.

In the Amiga writeup, it states clearly ms, being microseconds.  I thought initially they ment nanoseconds as well, and double checking on the other OS's, they were rating their context switching in ns, not ms.  So, Amiga either still doesn't measure up, or *really* doesn't measure up.
