--k+w/mQv8wyuph6w0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi, I would like to change the default value of BUFSIZ to 8192. After testing various applications that uses BUFSIZ like changing it in libmd I can often see performance improvements: For example with md5(1): Current BUFSIZ (1024) 0.13 real 0.04 user 0.09 sys New BUFSIZ (8192) 0.08 real 0.04 user 0.03 sys sha256(1): Before: 0.44 real 0.39 user 0.04 sys After: 0.37 real 0.35 user 0.01 sys This is done on a small amd64 Lenovo S20 laptop Review available here: https://reviews.freebsd.org/D2515 Any opinion?
