Playback from memory lag
« on: May 14, 2010, 10:25:49 pm »

Hi all,

Not sure about this one, kinda strange......

Just built a new HTPC and I have it running smooth with newest Nvidia drivers. However, with pre-buffer set at the stock 6 seconds, I was seeing huge buffer times and even a lockup when trying to play 24/96 FLAC over LAN. I have a strong G connection at a rate of 56MBps .....

When I disable playback from memory, playback is INSTANT. No buffering or dropouts or bogging down MC. I have enabled playback from local location etc. and all drives are mapped.

Maybe this is normal as it must load these large 2000-4000kbps FLACs into memory, but it really lags excessively, like 30 seconds and this is a DDR3 1066 board albeit w/ ATOM 330 dual-core.

It's pretty snappy w/ new vid drivers like I said. I like the memory playback feature but I was shocked at this; happy at least to have this remote client now feeling like my old HTPC which was the master.

Anything I can provide? I'll try to bench the system with MC bench tool and windows experience now.

Playback from memory takes extra resources.  This isn't a bug, it's just the way it is.  You're trying to pull 100's of MBs over a slow wifi connection, which is going to take time and CPU.

If it's slow, I would disable the option.  Over a network, I can't think of why memory playback would be better.

Thanks Matt! That's good news and what I suspected.

My Atheros 9852 is bad and will only side the g side of my dual band router. When I get the new mini PCI-E card installed I'll try again for kicks and see if the upped bandwidth is enough to use memory playback.
