Nate Lawson 4cdb148352 The mbnambuf routines combine multiple substrings into a single ... long filename. Each substring is indexed by the windows ID, a sequential one-based value. The previous code was extremely slow, doing a malloc/strcpy/free for each substring. This code optimizes these routines with this in mind, using the ID to index into a single array and concatenating each WIN_CHARS chunk at once. (The last chunk is variable-length.) This code has been tested as working on an FS with difficult filename sizes (255, 13, 26, etc.) It gives a 77.1% decrease in profiled time (total across all functions) and a 73.7% decrease in wall time. Test was "ls -laR > /dev/null". Per-function time savings: mbnambuf_init: -90.7% mbnambuf_write: -18.7% mbnambuf_flush: -67.1% MFC after: 1 month		2005-03-11 23:27:45 +00:00
