Hi all,
I am currently porting a Queuing System (fair scheduling and load
balancing) to FreeBSD which we have written for Linux. For this port I
need to know how to get a FreeBSD machine's current free memory, i.e.
the maximum amount of memory a program can currently use without
driving the machine to (heavy) paging activity. (This is provided in
/proc/meminfo under Linux.) Currently I am using the formula (using
sysctl variables):
(vm.stats.vm.v_page_count-vm.stats.vm.v_active_count)*(vm.stats.vm.v_page_size/1024)
but I suspect that it might not be correct...
Regards,
Bernd
