When I use pingboost 1 or pingboost 3 on a P4 1.7ghz - 1gig ddram - I see alot of choke - with one 20 player server running - CPU has 256k cache - I do not see this or need pingboost on CPU's using 512k cache nor on Intel Celerons 1.7ghz having 128k cache (using Pingboost 1) - no choke occurs... Using Redhat 8 - with all up2date crap install - minimal install - no GUI / XWin, etc... I use the P4 1.7ghz - Gen. Intel 256k CPU cache and if no pingboost specified the FPS is around 49-50 - with pingboost 1 - it jumps up to 97-99FPS - but see extreme choke - only 1 hlds process running on this box.... I'm one confused mofo now.
