Performace guidlines (tipps)?

Hi!
I want to write some gnu-apps which should be primary optimizied for gcj.
Are there some performance tipps whats better and faster? Are there
somewhere written guidlines avaible?
I'm currently using gcj-3.0.4. Will an upgrade enhace performance over 20%?
one example:
is this better:
class c;
while(n>m)
{
 c=new class();
}
or is it better to create the "class c;" in the loop.
I hope you can help me writing really good, fast and stable gnu-proggis
for my school.
