DragonFly bugs List (threaded) for 2004-11
Re: Process launch problem with DFLY
It's more likely to be the fact that the process's interactivity
heuristic is classifying the process as a batch process rather then an
interactive process. There is also a known priority roll over bug which
I just fixed a day or two ago but if you are not using 'renice' you
wouldn't be effected by it.
'ps y' provides useful information in this regard. 'PRI' is the
dynamic process priority, where *lower* numbers mean higher
priority (faster) and higher numbers mean lower priority (slower).
The interactivity measure is IAC. Negative numbers tend to mean that
the process is interactive while positive numbers tend to mean that the
process is batch. Numbers hovering around 0 mean that the system is
not really sure *what* the process is. Note that even in large builds
many of the longer lived 'make' processes will appear to be interactive
because they run only sporatically.
The numbers only apply to normal processes, not pure kernel threads.
