Hi, I have a strange problem here. I have Slackware 14.1 installed its multi-lib on a 120GB Samsung EVO SSD. I also have Windows 8 on a 1tb wd black( only for when my nephew comes over so we can play all the latest pc games, otherwise it would be all slack). I have 2 other wd black 1tb drives and a 2tb external usb 3.0 drive all three drives are formatted with exfat( don't ask why, just one of my bright ideas). Anyways, when I do filecopy operations from drive to drive I get about 3%-15% cpu usage on the exfat volumes, compared to 4%-6% on the ntfs volume, which I can live with. But when I launch qbittorrent while downloading (verizon fios 75mbps) I get 80%-100% cpu usage and it actually seems to be limiting my overall download speed because of this to a measly 5MBPS (that's megabytes not bits). So this is not the actual qbittorrent process having high cpu usage but the fuse exfat process having extremely high cpu usage only when downloading in that program. Googled this for hours can't find a fix. Anyone know whats up with this. Really need some help here any input would be appreciated.

have tried to limit connections on qbittorrent? there are plenty of other clients as well, but if you want to stay with qbitttorent you really should stick to ext3/ext4 that is known to work properly.

Limit connections? do you mean global connections? I'm trying it now. do you have a specific number in mind? I had it set very high considering my connection and the fact that I seed regularly so I keep them high. Am setting them all to 50 now. Nope at 50 for everything its still extremely high, no change. I like qbittorrent because it has way more options then transmission and its the closet to utorrent on windows. Any more advise? Thanks for the reply btw.

switched to deluge witch causes the same problem, no one ??? what i don't understand is why are only torrent clients causing this problem when i copy a file everything is fine.

reducing the disk cache seems to have an impact. but it also seems to reduce the overall download speed. actually i was wrong there is no difference.
