Reply to thread PMT eats CPU time? What on earth are you on about? What part of of it eats the CPU time? It can't be the context switching - every multitasking OS does that - including RISC OS, and the overhead of catching a timed interrupt and doing the context switch there can be made very lightweight indeed. In most OSes, PMT increases throughput massively. As for BeOS: 100MHz of *what* ? Just saying 100MHz is meaningless. And considering I've worked for real-time OS companies (QNX in this case) I can say for definate that real-time PMT schedulers are much easier to write than CMT ones, and are almost always significantly quicker. nunfetishist on 29/7/03 12:48PM [ Reply | Permalink | Report ] Please login before posting a comment.

Having pieced together the housing, Peter puts a legacy RISC OS machine through its paces as an internet-facing server.  11 comments, latest by jess on 3/12/08 2:07PM.
