Strange. While stress testing 3.4.2 before release I had quite the 
opposite experience. No nice graphs to include, I just watched the XFCE 
CPU graph applet, and found it used ~50% less CPU than with 3.4.1 and 
the same configuration (standard openSUSE syslog-ng config with network 
source and destination added).
