High CPU Usage When Deleting File

The question, of course, is when it's at 100% usage does it mean it's also using every single CPU core? of around 15-20°C . I was trying myself and looked at "top" at the same time that displays ressource usage under Linux. Member dweeezil commented Jan 19, 2016 @behlendorf Very interesting. http://hosting3.net/high-cpu/cmd-exe-high-cpu-usage.html

If so, then that's a lot of system resources for a single app to be using. I'm not familiar with Total Commander itself, nor am I 100% sure what extra functionality this "orthodox file manager" (i.e. The command will take some time to finish so it might be best to start it when you aren't going to be using the computer for a couple of hours. When I tried deleting the file in safe mode the dialog box tells me it is deleting a 874 mb file but it then freezes as it reads "discovered 0 items

The hard drive is an SSD, if that makes any difference. And i mean it is the 1 program that makes file management a million times easier and faster! Among my repeated tests, sometimes the load reach this high number, sometimes it goes up but remained in single digit.

I have little time have not been really been able to post information, but today I have some time finally (plus getting tired of it). When it's booting my keyboard becomes unresponsive so I have to wait for the countdown to run out (can't just hit enter into boot normally). I cant drag it into the recycling bin. We could tell if someone with a reproducer runs /path/to/funclatency -f spa_sync 120 during the time the rm operation is unblocked, kills it when rm unblocks and posts the output.

The delete took a long time (>15 sec.) and I saw a httpd process that was running at 100% cpu usage over that time. In this test, it is Amazon AWS EBS but the problem happened with ephemeral drive as well.

As to unlinked set, why would this operation be bypassing it?

It occurred when uninstalling one program. What we've seen is performance of these write ops (let's call it sideload I/O) would drop to zero.

Once the menu comes up, choose safe mode and when you get to safe mode, try deleting the file. If the above looks like the same issue ZoL is experiencing - we are prepared to try upstreaming our approach to @OpenZFS ahead of our normal upstreaming schedule.

The solution we have tested (with positive results) creates a relatively simple throttle for how many "free" ops we let into one TXG. Maybe Microsoft will add this to Windows 8..._________________Author of Total Commander http://www.ghisler.com Back to top ghisler(Author)Site AdminJoined: 04 Feb 2003Posts: 33185Location: Switzerland Posted: Tue Apr 06, 2010 9:42 am Post subject: SHOW ME NOW CNET © CBS Interactive Inc.  /  All Rights Reserved. page Home Forum New Posts FAQ Calendar Forum Actions Mark Forums Read Quick Links Today's Posts View Site Leaders What's New?

It's not possible to skip files in PreDeleteItem(), only accept the deleting or abort the entire process.

Contributor alek-p commented Jan 20, 2016 @dweeezil I should have mentioned that we have a separate patch for the unlink blocking problem. That funclatency tool is from brendangregg/perf-tools#43. You're aware that we're in 2010? I've googled for hours and i never found any solution...

Ah, and another weird thing, setting TCs process to lower priority actually speeds deleting up. After that I decided to connect the drive via eSATA because of the speed increase.

Now, I know its because the CPU spins up to 100% and it will heat up because of that, BUT... After that I started deleting the .wav files one by one. All rights reserved. Member ryao commented Jan 18, 2016 @dweeezil Why would extreme overhead in creating and destroying various objects cause everything to stop until the rm operation has finished?

As a results when deleting large files we end up filling consecutive TXGs with deletes/frees, then write throttling other (more important) ops. Thanks! What can be the cause for this high cpu usage? Here is another article with additional steps you might try.
