Description Bastien Nocera 2013-04-04 21:35:47 UTC 
After the fixes to the daemon (bug 675181), we don't crash anymore reading movies from smb locations, but the performance is pretty bad, especially compared to using the gvsf-fuse backend that sits on top of gvfs.

Disabling the read-ahead in gvfsreadchannel.c:read_channel_readahead() (by making it always return NULL) fixes the performance problems.

This particular bug might be fixed once bug 697289 is fixed, or we would need a way to disable read-ahead for a particular stream, which GStreamer would use as it already does its own buffering and read-ahead.

I don't seem to be able to reproduce this. I'll reopen when I can get a test case.
