Subject: Why tcl optimization conservative? - DN [1]

Ed Ohsone <eosn@rahul.net> - 30 May 2000 - comp.lang.tcl

 I found the default CFLAGS was given -O in compiling tcl/tk8.3.1
 when I compiled them with gcc.

 Most apps use higher level of optimization and in many cases
 it makes substantial difference in performance.

 For example, blt2.4s uses -O6 with gcc by default.

 If people benchmark tcl/tk performance with the default setting,
 they may not be getting the full potential of the language.

 Is there any reason the source packages need set the default to "-O"?
