"Stuttering" video when actively downloading torrents on ubuntu?

Need some advice on how to fix the brakes in the video playback when running torrent on butobetonnyh distro. The situation is this:


1. Installed different Ubuntu versions 11, 12, 13 and Mint a couple of versions.

2. Iron i3 and 8Gb of memory

2. The system drive ssd 64Gb

3. File storage 3 x 2Tb hdd combined lvm to ext4.

4. Torrents swinging on 9-10 MB/sec


While the torrent is enabled and actively shakes, the video is running on the playback consistently stutters every 2-3 seconds. Viewing becomes impossible.


I assume that this is due to the intense unordered data records to disk and the process of the player is displaced so much that it causes stuttering during playback.


I will be glad to ideas, solutions or links to useful articles.

To increase the memory limit in the settings of the torrent client?
Thanks for the advice, tonight I will try. - sasha_Borer commented on October 3rd 19 at 02:47

Try to reset the whole movie on a virtual disk in RAM. If the problem is with the HDD (and probably is), it will help you.
The idea is good, but because of high speed download — need to download something really big, there's a ramdisk may not be enough, but for the idea thanks, I'll try the folder to under-inflated torrents on the ssd to host — it would definitely be faster. - sasha_Borer commented on October 3rd 19 at 02:49
Please! When dostatkem complete a variety of storage media (HDD, SSD, RAM) it makes sense to separate them for IO operations.
Here's another idea to add additional storage on Flash/SD card. - sasha_Borer commented on October 3rd 19 at 02:52

Hard drives under cooling? Again, what specifically, for example, my genovy WD (on 2Tb) can be shut up very much (about 5Mb/s on stream, periodic defragmentation saves the day, but I have NTFS) if, in 2 threads dealing with it, so he moved to the multimedia player. Again, can adversely affect heating.

Well, to solve this problem is possible unless the constraint speeds in the torrent tracker. You yourself probably know that it's the HDD, the head one. And when she has actively run in one, in another place, normal reading speed is reached. It is possible of course to play with the caching, but will not help here.

Well, probably you wanted to say 2Tb hdd x 3
thanks, fixed the typo on the 3 x 2Tb hdd.

Articles online personal and painful experience had taught buy WD, so I have everything else, but not WD =)

About speed limits — it will be an option if I could find a suitable solution, because now even put it on pause. In the absence of a good solution probably will have the same limit, which is better than a full pause. - sasha_Borer commented on October 3rd 19 at 02:51
If you are using Transmission — there is a convenient button with the bug, for fast temporary speed limits. - sasha_Borer commented on October 3rd 19 at 02:54
Well WD Black work fine, even very good, but genovia slaughter them to reflash the idea is necessary. - Roscoe commented on October 3rd 19 at 02:57

The simplest way is to increase the cache of the player.
Tried — did not help, but definitely try to experiment again. - sasha_Borer commented on October 3rd 19 at 02:55

You can still bring torrents on the selected filipovice, which, for example, separately to the router (with torrents) are connected.

Judging by the period 2-3 seconds, then plugging occurs when odczytywanie of the movie in the video buffer of the player, and probably stems from the fact that the disk is overloaded on the read/write.

You can dig in the following areas:
1) use a player with proactive reading
Ie to pre-fill the buffer, but not immediately before the previous ended.
2) before viewing copy of the film on a separate physical disk (second HDD) or in RAM disk
3) to reduce the priority of the torrent to the operation of the read/write waiting for the player.
