SabNZB 2.3.3 drops to 1/8th speed after 5 seconds

[sidekick2]

I normally download at ~90-100MB/Sec w/2.3.2 and after the installation of 2.3.3, the first 5-10 seconds speeds ramp up to normal, and then drops to 13 MB/sec, and holds there. I've reinstalled twice, and rolled back to 2.3.2 to get back my 100MB/sec speeds. I've gone thru the settings looking for what might be holding it back, increased article cache to 4G, but something goes drastically wrong after running for a few seconds.

I have 2 Usenet sources active, 60 threads & 20 threads, gigabit service.

Right now, I'm sticking with 2.3.2.

What is the CPU usage when it's slow and how many cpu cores do you have?

Could you give this modified version of 2.3.3 a try?

Trying to pinpoint if it's the C-code or the Python part that's giving you problems.

I have an I7-4930k, 6 cores / 12 HyperThreaded running at 3.40Ghz. That version above works. CPU is at 17-20% while running. Just downloaded some 50G without issue.

Could you try some more for me? This way I can identify where it went wrong:
Test1: https://github.com/sabnzbd/sabbuild/rel ... -setup.exe
Test2: https://github.com/sabnzbd/sabbuild/rel ... -setup.exe

Okay, this sucks. I can't reproduce the issue now. I've installed test1, test2, and went back to the released 2.3.3 trying to get a fail. I don't know if it's a fluke or not, but Test1 seems to be riding ~5MByte/sec faster. What's changed on my side, is my 2nd provider usenet sub has expired, so I only have 60 threads. I've downloaded ~200G, dling garbage going back and forth between releases.

I'm going to re-install the released 2.3.3, and let that sit for a few days, and see if it pops up again.

I appreciate your effort, but I'm at a loss right now to explain why I can't get a fail.

Thanks!
