What scheduler is currently the most complete for SMP/multi-core > capable processors? 4BSD is stable and works well. Jeff R just committed a major overhaul of ULE and it MAY now perform a bit better and has been reported to be stable, now. But it is still experimental d a work in p progress. > 2. Do I need to add some sort of compatibility layer for 6 going to 7 > (similar to compat_5)? There is COMPAT_FREEBSD6, but there is no compat_6x port at this time. Due to the instability of ABIs in current, be prepared to do a lot of port building. > 3. What are (briefly) some of the major changes for the ABI/API going > from 6 to 7? Someone mentioned some changes to the ABI when I emailed > the hackers@ list previously, so I was just curious. Lots of ABI changes. Read /usr/src/UPDATING for the details. ABI changes should all be mentioned there. > 4. How is SATA support for SIS motherboards under 7? Decent? No idea. I have neither a SIS mobo or a SATA system. > 5. Is 7 running gcc-4.x? Not yet, but it should be coming fairly soon. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
