There are reports from around UCSD that you can read one 8-channel SF with no trouble but can't begin to read 8 1-channel ones separately on a "reasonable" IDE machine. I'm hoping to get a chance to look at this (and a student is also threatening to get involved.) So the situation might improve soon.

In fact I know that I can read easily more than 24 monos tracks with "broadcast2000" which is a multitrack recorder for linux... Why cannot get this kind of performance with PD ?
So 1) have you the same poor performance with PD disc i/o objects ? 5) how much tracks can you play on which hardware ?
I am able to read 24 tracks easily, writting is another issue. What computer do you have ? Its on a 500 Mhz, IDE disk with DMA enabled.
- Is it specific to pd linux ?
- Do i set something not as it should ?
- Is it because of no special optmisation in pd for disc i/o ?
I am not sure about the builtin objects (readsf~ writesf~), but I can't think of any further optimization in sfread~ and sfwrite~. (Doesn't mean that there is no way to do it faster ...)
