	Hi everyone. I am using a Ryzen 9 3900X, 32 GB with 12c/24t and just for the fun of it I recently installed a second partition running Ubuntu. The run times between the two OS vary considerably. While under Windows the wu's take around 3:17 hours to complete, they finish in around 2:47 under Linux. Did anyone else notice this behaviour? This seems to be true also for other projects like Universe and MLC. ____________

	Absolutely possible, and the difference between Linux and Windows would be even more extreme on multi core processors, such as 64-core AMD Threadripper 3990X, where Linux is over twice as fast as Windows on multiple benchmarks. Windows kernel sucks at anything over 8 cores, frankly.

	Correct, TN-Grid runs faster under Linux. At Universe@home, the BHSpin tasks run much faster on Linux as well (over 50% IIRC). Projects at WCG that use the AutoDock Vina software are around 50-60% faster on Linux (such as the Smash Childhood Cancer project, which has no work right now). ____________
