The request queuing for SCSI is very different to >that for non-SCSI devices. Different enough that you feel its likely to explain the significant difference between my experience and that of both Benno and Juhana when trying to record to disk ? Is it different enough to explain why the buffer cache write-behind batching doesn't seem to show up as a problem for me ? Stephen - thanks for paying attention and giving us time on this. I know you have a lot to work on, and that HDR is not what most people consider to be a hot Linux application; our little minority is pretty fanatical :) The application I have ("ardour") stands in relation to existing HDR systems in the same way that Linux or *BSD-based routers stand to Cisco h/w, with the difference being that very few people own the dedicated h/w yet, and so we have a real chance to provide a genuine, new service for people by getting this to work. --p
