VLC is one of the most popular media players people love to use for its strong power to play any video including the MKV container files. But sometimes, powerful as VLC will encounter MKV playback issue. Many feedbacks unveiled that VLC was very slow to play MKV once in a while. Below is just one case from VLC forum.videolan.org:
"The VCL is very slow when play .mkv videos comparing to.
I tried many video files, one example is the “NBC 2008 Beijing Olympic Opening.mkv” which has only 720p format. On one not so fast PC (windows 7) it can be barely played smoothly with other players, with VCL only couple of frames per second and many places stops for seconds. I have 5 PCs in the family, only one fastest PC can play it with VCL smoothly.
I wonder why?"

There are many reasons to lead MKV files playback stuttering on VLC. Maybe your computer is too slow, then your VLC takes too much memory resource to run while VLC can’t handle your MKV files with certain codec. Now, let’s the solutions to solve MKV choppy playback issues on VLC.
Solution 1: Disable loop filter for H.264 decoding
VLC can play almost all media formats but it does not mean that its codecs are equally efficient at playing all of the. Therefore, one reason that VLC plays MKV files slowly is that libavcodecs H.264 decoding used in VLC isn’t very efficient. There is one trick you can try: You can speed up the H.264/MPEG-4 AVC playback by disabling loop filter for H.264 decoding. To do this go to Tools -> Preferences… (set Show Settings to All) and Input / Codecs -> Other codecs -> FFmpeg and in the drop-down box for Skip the loop filter for H.264 decodingchange it to All. Remember to press Save to save VLC settings and restart VLC after that to make sure changes are enabled.
Solution 2: Get VLC Alternative
VLC will take a lot of memory resources to run. It is surely unable to play most HD MKV videos smoothly on slow computers (those with 1Ghz processor or below). It proved that MpcStar can play MKV files smoothly even on slow computer. MPCStar is a universal video player that can play most formats of films downloaded from the internet. To ensure smooth playback and not get weighed down with too many codecs, MPCStar contains only the major codecs including Media Player Classic, FFDshow Codec Pack,
RealPlayer Codecs, ActiveX controls, QuickTime Codecs and DirectVobSub (a.k.a. VSFilter). The only problem is that these codecs are regularly updated and there appears to be no automatic update function but overall, this is one of the simplest and most powerful players I’ve tried since VLC player.
