Has anyone noticed a reduction in their results after installing Win10 v1903? I upgraded windows versions on my systems Friday the 19th and the past 3 days have seen a ~18% reduction in total run time and results while the points generated has been reduced by ~11%. I noticed there was some system-wide WGC maintenance on the 18th, but I can't imagine the maintenance would somehow reduce the amount of work the computer's doing...

BOINC/WCG do 2 sets of timekeeping, one being the runtime AKA elapsed time, which is the time BOINC was running the task, and CPU time, the time BOINC was doing actual computing. Earlier W10 was getting 97-98% efficiency, the ratio of CPU time against elapsed time, but now its sunk to 93/94% on my system. More overhead regardless of efforts by MS to minimize those
Certainly recommend minimizing your web browser whenever nt at the computer. These apps particularly suck CPU time by the boatload even when not in use but full screen in background. |

After I updated to Windows 10 V1903, I found that the vsmon.exe process from Zonealarm was using nearly a complete CPU thread. I have had to remove Zonealarm from my PC until a future release of Zonealarm behaves correctly. As vsmon.exe is a 32 bit program it also seemed to interfere with and slow down other 32 bit programs.

Never figured out why 1903 reduced performance so much, but the good news is 1909 increased performance to previous levels and then some. We're up almost 25% across the board (+25% run time, +14% points generated, +24% results returned). Moral of the story is; go get that 1909 patch I guess?

Yes in deed, at night hitting 99% again, but, in this installment they've broken OneDrive, for me causing major latency if not minutes of complete screen-freezing, mouse locking, so I kill it during daytime. That piece of software needs scheduling feature and bandwidth control. MS even boasts about it now grabbing all that it can particularly on fast lines.
