Yeah. But as long as it is only a 10 -> 15% performance problem. After
that is pays to change the design (IE the singleton design.. not too OO
but designed well).
As per speed. JDK 1.1 is missing some things from StringBuffer (IE
replace). I created a StringUtil that is in Jetspeed that adds this
support. It will scan a whole string and replace as it is needed. When
you do things like look for http URLS within an doc and make them all
<a> urls it is a big performance improvement.
