Poor performance

I have upgrade web server from 4.7 to current (cvsup date 2003.12.08.06.40.00)
and have degradation performance.

apache (1.3.24) run many cgi (perl).

If running make kernel -- it's running wery slooowly.

I see many system time (average 35%), idle time (average 30%) and 
many (average 15) locked process (at *Giant)

What additional information can help to resolve this problem?
