*:syntime*
+ 
+ This is aimed at authors of a syntax file.
+ 
+ If your syntax causes redrawing to be slow, here are a few hints on making it
+ faster.  To see slowness switch on some features that usually interfere, such
+ as 'relativenumber' and |folding|.
+ 
+ To find out what patterns are consuming most time, get an overview with this
+ sequence: >
+       :syntime on
+       [ redraw the text at least once with CTRL-L ]
+       :syntime report
+ 
+ This will display a list of syntax patterns that were used, sorted by the time
+ it took to match them against the text.
+ 
+ :syntime on           Start measuring syntax times.  This will add some
+                       overhead to compute the time spent on syntax pattern
+                       matching.
+ 
+ :syntime off          Stop measuring syntax times.
+ 
+ :syntime clear                Set all the counters to zero, restart measuring.
+ 
+ :syntime report               Show the syntax items used since ":syntime on" 
in the
+                       current window.  Use a wider display to see more of
+                       the output.
+ 
+                       The list is sorted by total time. The columns are:
+                       TOTAL           Total time in seconds spent on
+                                       matching this pattern.
+                       COUNT           Number of times the pattern was used.
+                       MATCH           Number of times the pattern actually
+                                       matched
+                       SLOWEST         The longest time for one try.
+                       AVERAGE         The average time for one try.
+                       NAME            Name of the syntax item.  Note that
+                                       this is not unique.
+                       PATTERN         The pattern being used.
+ 
+ Pattern matching gets slow when it has to try many alternatives.  Try to
+ include as much literal text as possible to reduce the number of ways a
+ pattern does NOT match.
+ 
+ When using the "\@<=" and "\@<!" items, add a maximum size to avoid trying at
+ all positions in the current and previous line.  For example, if the item is
+ literal text specify the size of that text (in bytes):
+ 
+ "<\@<=span"           Matches "span" in "<span".  This tries matching with 
"<" in
+               many places.
+ "<\@1<=span"          Matches the same, but only tries one byte before "span".
