+3  Q: 

AWT text measuring implementations

The Java 6 (J2SE) implementation of AttributedString, TextLayout, and LineBreakMeasurer classes use anti-aliasing properties and fractional math for metrics calculations. This causes a severe performance penalty.

What suggestions (for Cent OS Linux) do you have to increase performance? Such as:

  • A faster JVM (JDK 1.7, Oracle's JRockit, IBM)
  • A different AWT implementation (any?)

Thank you!

+1  A: 

Does the java.awt.FontMetrics class give any better performance? It may still be used by the classes you've mentioned, but it's a pre-Java 6 implementation at least.

@Ash: The code that uses those three classes is rather complex; someone is else working on the problem; if they can use a single class, I will let you know. Thank you!

@Ash: This is probably the only viable alternative, whether it works or not. Thank you.
