Hello, I was wondering what the status of the BUFQ_READPRIO & BUFQ_PRIOCSCAN kernel options are. The comment on all but the i386/amd64 kernel configs are that it is experimental, whereas on i386/amd64, BUFQ_PRIOCSCAN is enabled by default.
Does the comment need updating (I'm happy to do it) or is it deemed experimental on anything other than i386/amd64? I've been running the macppc 8.0_BETA kernel with the BUFQ_PRIOCSCAN option enabled for a couple of weeks without any crashes, I/O performance is bit of a different question in my scenario as the system is running from a USB flash drive. src/sys/arch/amd64/conf/GENERIC: # Alternate buffer queue strategies for better responsiveness under high # disk I/O load. #options BUFQ_READPRIO options BUFQ_PRIOCSCAN vs # Enable experimental buffer queue strategy for better responsiveness under # high disk I/O load. Use it with caution - it's not proven to be stable yet. #options BUFQ_READPRIO #options BUFQ_PRIOCSCAN Sevan
