Hello, Freebsd-geom. The same idea about pre-reading in case of providers with multiple consumers (BTW, I think that terminology here is swapped): it looks good to issue pre-read only if target consumer is idle. Is here any way to determine that? For example, ehat exactly means percents of load in gstat output? Can I rely on this statistics, and how should I get it in-kernel? --=20 // Black Lion AKA Lev Serebryakov <lev@serebryakov.spb.ru>
