What can be done do to speed up the EPG load?
It seems that kodi should be able to cache the EPG on the client side and only call for a refresh of the cache every so often.
Right. I wasn't reporting a problem on a particular platform. Just an observation that Kodi appears to reload the entire EPG nearly every time it's run. it seems that successive runs the EPG should already be cached and immediately available.
No problem, it's just that you posted in the support forum so I assumed you had a specific issue.
Kodi will cache the EPG from a backend in its EPG database which is considerably quicker to load than from the backend (at least with my mythtv backend on Krypton beta 6). (see System->Settings->Pvr & Live Tv->Guide and de-check 'don't cache in local database'.)
Edit: You need to have settings level at 'Advanced' or above to see this option. (Using Estury skin start with 'Gear icon' then Pvr & Live Tv Settings->Guide)
I am under the impression that Krypton is slower at this than Jarvis was, but haven't yet found the time to investigate why. I know Krypton now does some of the EPG prep as a background task while the guide is loaded and this introduced a lot of deadlock issues (mercifully mostly fixed in Beta 6). Probably it is something related to that.
The strange thing is not only are my raspberry PIs slow, but so is my Core2 development machine. Normally slow things on the Pi are fast on the Core2...
Using Kodi's EPG database does not make much sense if the addon has already a db. I don't think any Kodi dev is actually using the DB cache.
