After considerable testing today, the issue appears to be related to the specific partition whether or not it's bootable. I must have been downloading to a different partition when I marked the problematic partition unbootable. I believe I reported incorrectly in post 2. Maybe that's part of the issue? I'm confused! :) What's special about a bootable partition and the file i/o of a bit torrent client? Hmm, my direct download tests never created a 1 GB file. With either package, copying the existing download to a non-bootable drive and restarting transmission results in ~ 1.5% CPU usage at 200+ KBs. Since the CPU usage and download rate bounce around, that's a very rough estimate. New ntfs-3g: With ~1 GB downloaded, I see ~55% CPU usage at 220 KBs. Old ntfs-3g: With ~700 KB downloaded, I saw ~65% CPU usage at 240 KBs. There is some improvement with the new package: CPU 2 seems to be handling the rest of the system's needs. Oh, this is a two cpu machine, and from watching System Monitor, it appears that the high usage is restricted to CPU 1. Earlier, when I had over 2 GB downloaded, the maxed CPU usage limited my download rate to 100 KBs. I.e., it hit 90%+ at around 900 MB downloaded. On my sytem, CPU usage is ~10% of download size at 200+ KBs transfer rate. However, as the downloaded file grew, so did CPU usage. I started a fresh download and mount.ntfs wasn't hogging the CPU. Something I hadn't noticed before, CPU usage is related to download size as well. part file grows as it's downloaded.īefore updating ntfs-3g, I tested the old version again. The direct download was done in Firefox, which seems to allocate the file on the fly since the. However, the file had been partially downloaded by transmission before deluge was installed and tested on the remaining portion of the download. So I would expect the same usage for a torrent file.Īs mentioned, deluge was configured for full file allocation.

May or may not matter, but the ntfs partition in question was an ACTIVE windows system partition. Deluge was configured for full file allocation. Downloading with either transmission or deluge bit torrent clients to an ntfs partition results in 90+% cpu usage.
