I guess a memory leak is unlikely since memory usage returns to normal after downloads complete. The cache usage never goes above ~20 MB. Still, it seems like there must be some problem related to memory / caching / internal configuration if the first download after a restart works fine, and all sub...

It sure seems suspicious that the first download on a fresh daemon start works great, and all subsequent downloads slow down. Could this be a symptom of a memory leak or some volatile configuration issue?

I don't think it's a disk bottleneck. Even with all folders (temporary/completed) set to the SSD, I get the same behavior. And I know that it _can_ write faster, it just doesn't, because the first job after restarting the server downloads at full speed (>40MB/s), and all subsequent jobs top out at 1...

Ugh... there is definitely something weird going on here. That feature branch is better, like I said the first download goes super fast until the very end where it trails off, but every subsequent download is as slow as ever. Although they don't show the spike-and-tail-off behavior of before, they a...

Thanks lot, I'm pretty sure that solved it. I say pretty sure because at first it behaved a little inconsistently. After installing from source and switching to that branch, the first job started very fast and then slowed to 15MB/s. All subsequent jobs topped out at 15MB/s. But after restarting the ...

Hah, yeah re-running Pystone gave a much better result, no idea why: 194685. I re-ran it a few times to be sure, similar results. I agree HDD is slow, not sure why, I'll look into that separately. But I don't think it's the issue here. I changed the completed downloads folder to the SSD and nothing ...

Thanks for replying! It's an Intel NUC D54250WYK: Core i5-4250U, 4G RAM, SSD temp dir + HDD completed storage. Specs: System performance (Pystone): 73879 Download folder speed: 106 MB/ Complete folder speed: 36.8 MB/s Test downloads look exactly the same as ordinary downloads, they start fast (30MB/...

I'm trying to figure out why Sabnzdb downloads are slower than expected on my HTPC: 15MB/s sustained, whereas a desktop computer on the same network can get 40MB/s using the same server and configuration. I know that many people would kill for 15MB/s, and obviously I'm not complaining about it in th...
