I have this bad feeling about net.inet.tcp.tcprexmtthresh=1 being added to the bogus pile of sysctls that should be changed which is sent to every person who asks how to tune their system. (Just look back through mailing list archives to see how man tweaks people are making that shouldn't be made.)
