FreeBSD SMP on 4.x + usage monitoring

Hi all,

Very important to me is are we able to monitor or, at a minum, to be sure, thread-enabled application is using more than just a single CPU. For example:

1) I compiled linuxthreads from ports direcotory.
2) I compiled Mysql 4.0.18 Server, with linuxthreads , again from ports collection
3) SMP enabled kernel

What I observe, with ``top -I`` is mysqld using just one CPU, during a single bulky, SQL query.

My questions are:
1) Is top the proper way of cpu usage monitoring
2) are there any other tool for real time monitoring for SMP

Thanks in advance..
