Aftv kodi slow down

Hey all
I'm having some issues with both my fire TV and fire TV stick. I've installed kodi, plus genesis and a few other add ons on each and changed the skin (aeon nox silvo on stick and titan on fire TV gen1), updated the library with some of my favourite shows and over time it seems to be getting slower and slower, particularly when I try to add a new repo, along with freezing during startup updates if I'm trying to do something at the same time, eg. Watch a TV show.

I wondered if anyone else had been having any similar problems? And whether there was any possible fixes?

Thanks all :)

FTV (gen1) and Kodi 15.1 stutters ???

So I had Kodi 14.something on all my fireTVs with a shared MySQL on my net. Memory is hazy but I think it was stock Kodi not SPMC, but I wouldnt bet my life on it.

I dont remember any stuttering, and even tested / watched 1080 as working ok.. I am not a super highbite rate full size BluRay type consumer and I could be wrong but I just remember it working 99% of the time for the files I threw at it. Enough that I was happy as a media center in all rooms.

Just because I thought I maybe was missing out, I upgraded to 15.1.. Tested Kodi was running on one box OK and as the MySQL all has to match, I updated all my boxes. They are all hard wired BTW. They seemed OK and first few things I watched I noticed no issues.

Just noticed stuttering playback on a series.. Assumed it was that series as high bitrate.. Now soon after and seeing stuttering on another series.. Looking at my files they are 'only' 720p files (MKV).. I am sure I was playing 720 fine before the update. Other far higher bitrate MP4s seem to play just fine.

Is 15.1 somehow worse on the fireTV than 14.x ??
Is 15.1 Kodi not HW accelerating and maybe I had SPMC ??
Is 15.1 Kodi on the FTV worse with MKV's ??
Are others using 15.1 and playing 1080 content smooth ??

Just looking for some input before I start the process of testing builds or rolling back. Its a hassle to do all the boxes and its a live system in the house.

Thanks.

Kodi on Fire stick, 100% cpu usage after inactivity

I have been using the Kodi on my fire stick for several months and it has been working great however lately I have noticed that if you leave it running idle for a while the menu is very sluggish. When I check the cpu usage, both cores are at or near 100%. I need to restart Kodi for it to work. I backed up my settings, uninstalled Kodi, installed a newer version, restored the backup settings and it still does it. Anyone experience this type of behavior with their Amazon device running Kodi? Thanks.
