- I need to do fast i/o (especially writes) to disk from/to a network
- peripheral. What is the best way to do this? (System=ISC/Sunsoft
- System V.3). For performance reasons I think I want to do this in a
- driver, but I don't know how to get to the disk "legally". The access
- to the network devices is (depending on device) via DMA or shared (low)
- memory.
-
- It doesn't really matter if the data on disk isn't accessible via the
- filesystem, but it wouldn't hurt. I assume I don't really want to go
- through the buffer cache (again for performance reasons) but I could be
- wrong.
-
- Killing performance for the system users is not a big problem, but I
- don't want to lose interrupts, etc.
-
- Thanks for any hints,
- Eric
