Measurements with PNG graphic

This snapshot shows the CPU load when a pvserver (process pvs) in an infinite loop draws the graphic as a PNG 1 time per second.

This snapshot shows the CPU usage when a pvbrowser client is added to the display. You see that the pvbrowser client is much bigger than the pvserver

This snapshot shows the CPU usage when a firefox client is added. Firefox takes about twice as much CPU time as pvbrowser and takes up about 3 times as much memory.

This snapshot shows the CPU usage when a chromium client is added. You can see that the pvserver (pvs) has increased from 7.6 %CPU without clients to 8.3 %CPU with 3 clients.
