[-- Attachment #1 --] In addition the candidate "head" patch does not include resizing of the dirty write buffers to prevent slamming the system's VM into paging. It does fix a number of other problems. There is a candidate against STABLE that incorporates Steve's patch and those further changes; the entire thread (long!) discussing it is here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=187594 Adding the write-buffer resizing against head would be very easy; there is open debate on whether it's the right thing to do or not but doing so has a materially-positive impact on performance for my systems.
