Synopsis: Poor file(1) performance State-Changed-From-To: open->analyzed State-Changed-By: edwin State-Changed-When: Thu Oct 21 20:53:01 UTC 2010 State-Changed-Why: The best patch so far without loosing features would be: -100 regex/c =^[\ \t]{0,10}call[\ \t]{1,10}rxfunc OS/2 REXX batch file text -100 regex/c =^[\ \t]{0,10}say\ ['"] OS/2 REXX batch file text +100 regex/c =^[\ \t]+call[\ \t]+rxfunc OS/2 REXX batch file text +100 regex/c =^[\ \t]+say\ ['"] OS/2 REXX batch file text which reduces the worst-case time from 1900 ms to 450 ms, full removal would reduce it back to 170 ms. Worst case scenario is the file aclocal.m4 in the contrib/file directory.
