BFQ I/O Scheduler Queued For Linux 4.12

[post-factum]

Same here. I didn't use bfq, but enabling blkmq helps cfq a lot. Performs much better than Win7.

Enabling blk-mq just disables scheduling at all now. So, congratulations, CFQ has nothing to do with this.

Thanks for the explanation.

It doesn't take much to outperform Windows in this regard. All Windows versions from 7 to 10 just stall completely here if I start a big copy or decompression task. Want to un-7z a 10GB file? The desktop becomes completely frozen for several minutes on end...

It's utter garbage :-P

On Linux, and especially with BFQ, I don't even notice the copy/unpack operation is going on.

Why BFQ won't be the default scheduler?

Good news. Windows stalls even with Steam. I'd love to see schedulers performance and latency comparison.

I never had this problem on windows 10 on my laptop...

Because Linux's main target isn't desktop, apparently. It took an awful fucking huge lot of time to get this merged as optional scheduler.

This is great, I can finally (eventually) show off to OSX users that keep annoying me with how on OSX is so smooth even with multiple programs open.

Agreed. Another fun one is opening a folder with say 3-4k sub-megabyte image files and waiting to eventually see thumbnails (a few hours later).

I've been using programs like FastCopy on Windows because it manages to move files without locking up the system (and are even significantly faster than normal copy-paste).

Not scheduler fault, but graphics subsystem perhaps (X)? However, os x is damn slow, so it's hard to believe.
