* cat(1) compiles fine at WARNS level 6.Dag-Erling Smørgrav2009-03-161-0/+1

* Teach cat(1) and cp(1) to use a larger buffer if enough memory is presentIvan Voras2008-10-301-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | in the system. A simple heuristics is used to detect what is "enough" memory: if number of physmem pages is greater than 32k (equalling 128 MB on machines with 4 kB pages). Typical immediate result of these changes is reduction in context switches and the goal is to increase efficiency by using large buffers: before: /usr/bin/time -hlp cat file1 > file2 ... 163 voluntary context switches 11194 involuntary context switches after: /usr/bin/time -hlp ./cat file1 > file2 ... 417 voluntary context switches 272 involuntary context switches Reviewed by: hackers@ (no objections to earlier version of cat patch) Approved by: gnn (mentor) MFC after: 4 months Notes: svn path=/head/; revision=184471
