How to find the usage of individual core cpu usage in FreeBsd server?
What command is used for that?
Thanks,

Hello there,
My mulithreaded application (which is too large to represent the source code here) is crashing after installing FreeBSD 7.1-RELEASE/amd64.
It worked properly on others machines (Dual Cores with 4GB of RAM - FreeBSD 6.2-RELEASE/i386).
The current machine has 2x Core 2 Duo... (1 Reply)

perlfreebsd - Perl version 5 on FreeBSD systems
DESCRIPTION
This document describes various features of FreeBSD that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.
FreeBSD core dumps from readdir_r with ithreads
When perl is configured to use ithreads, it will use re-entrant library calls in preference to non-re-entrant versions. There is a bug in
FreeBSD's "readdir_r" function in versions 4.5 and earlier that can cause a SEGV when reading large directories. A patch for FreeBSD libc
is available (see http://www.freebsd.org/cgi/query-pr.cgi?pr=misc/30631 ) which has been integrated into FreeBSD 4.6.
$^X doesn't always contain a full path in FreeBSD
perl sets $^X where possible to a full path by asking the operating system. On FreeBSD the full path of the perl interpreter is found by
using "sysctl" with "KERN_PROC_PATHNAME" if that is supported, else by reading the symlink /proc/curproc/file. FreeBSD 7 and earlier has a
bug where either approach sometimes returns an incorrect value (see http://www.freebsd.org/cgi/query-pr.cgi?pr=35703 ). In these cases
perl will fall back to the old behaviour of using C's argv[0] value for $^X.
