mkv or iso? mkv files are a bit quicker to seek.
I wouldn't expect the sdcard to affect buffering time (unless using buffermode=1 and cachemembuffersize=0 which would use the sdcard).
The network speed will affect it. May be worth checking with iperf from server to Pi. Should get around 90Mbit/s if all is good.

Thanks for the reply. I'm using MKV files ripped using MakeMKV so they are full-quality/bitrate Bluray rips.

I'll do some testing with iperf and see if I have nay problems. Thanks again!

EDIT: Oh, I almost forgot to mention but I have this little square in the upper-right with lots of colors in it that doesn't disappear? I just did a search and it looks like this is caused by under-voltage. I've ordered the official Pi power supply, but for now I'm using an Apple 10W (2.1A) PSU connected to a microUSB cable so that's strange to see the warning?

Thanks. After letting my RPI2 sit idle all night, it's showing about 15% idle CPU usage (using 'top' over SSH).

However, I'm still wondering if it's normal to see [Buffering...] for a few seconds when seeking around very large files. I'm using wired gigabit Ethernet and NFS. My over HTPC seeks around pretty much instantly.

I have no lag with my large files, but the largest are only 2GB or so. They are coming via SMB on a gigabit network, but the Pi is only capable of 100mbit. You can test your network connection by installing and testing with iperf. Try moving one of your big files to the microSD card, is the lag still there? I use 32GB Samsing EVO cards, they are great, I have no issues.

You can get a good network speed bump by using a USB gigabit adapter, but the Pi should not need that additional speed, it should pull things fast enough over the built in 100mbit ethernet not to matter. http://forum.kodi.tv/showthread.php?tid=...pid2111345

You can also increase the SD Card speed http://forum.kodi.tv/showthread.php?tid=...pid2063477 note I went back to 84, one of my RPi2s was unstable at 100 (no matter which card I used) and I wanted the settings to be the same for both my RPis.

Yes, that is an under voltage warning. I had the same, turned out to be the special 'high power' cable I was using lol
If you trust the power supply, don't rule out the cable, it bit me.

hvs_priority and v3d_clock
be removed from config.txt before testing?

If it helps, you should notice an improvement in both cases. Try without those settings first and then with if it doesn't seem to help.

without hvs_priority I get a lot of green artefacts and glitches
with hvs_priority=0x04000000 it's much better, but still some glitches visible
v3d_clock=400 improves behavior but still rare green artefacts and increasing discontinuity counter in tvh webinterface
after some minutes watching kodi starts buffering

With the same settings, do you think there is any improvement in today's build compared to previous builds?

I'm not sure, but maybe a small step in the right direction.

Just tried the 11-12 version and the hifiberry quit working. There was no option to choose it in the audio output. Tried the 11-10 version and it was working then. Had the option to choose pulse audio and it was working.

Edit: Sorry, not sure how the multiple posts happened.

awesome work..
just installed 1112
but i was wondering if there is anything i can do to increase the speed when trying to watch a BR.iso.. on the rpi2 it takes 2-3 mins before i get the pop up asking which stream i want to watch. with a lot of these lines repeating. other boxes its maybe 10 seconds.

So it works with #1110.
Doesn't work with #1112.
Is the Hifiberry working with #1111b?

There are no kernel config changes between #1110 and #1112. There is a firmware change in #1111, and PulseAudio is entirely disabled starting with #1111 (until the passthrough issue is resolved).
