This is a new thread - interesting perhaps only to myself?
In the past year, I have asked about the subject of "pacing" a couple
times without response. What I saw was that jnos took some time to
process stuff I thought should be quite quick. Certainly it is a low
level issue since jnos did *correctly* process...
Pacing is probably not a good word, task scheduling may be a better name
for the issue. I recognize that DOS and UNIX are both suitable
platforms for jnos and these OS's come with significantly different task
scheduling facilities.
In resolving the parameter issue discussed in previous mail, I created a
situation where I asked for DNS plus telnet services simultaneously with
FTPD services. The results were disappointing. At the OS level I also
placed a nice=-10 on jnos to force more aggressive scheduling and
quicker response. No joy.
Another observation on my site is that jnos has a miniscule demand on
the processor. When sorting the process list on the CPU-USEAGE
parameter, I have never seen jnos above position #5 out of more than 100
processes. Mostly jnos is below the 50% mark, many of the processes
above jnos are actually "sleeping"...
The question this brings me to is this:
Does jnos contain a task scheduling algorithm that is suitable for DOS
but may be redundant with linux task scheduling? Then if jnos does
contain a task scheduler, is there a way to permit higher CPU
utilization on a Linux platform?
