Interesting. Further testing revealed that sun-jdk-1.5.0.11's behavior |
18 |
is consistent on all amd64 procs. Despite earlier statements about it |
19 |
not failing on Turions. Compiling Tomcat 6.0.x with 1.5.0.11 on amd64 |
20 |
fails always, less memory is increased or compiler is switched to ecj |
21 |
from javac. |
22 |

23 |
Beyond that 1.5 and 1.6 seem to have the same default allocations, |
24 |
except for initial starting min value. 1.5.0.11 stars with like 4mb, and |
25 |
1.6 starts with ~7mb. Their max is the same default. ~64mb on x86, and |
26 |
~84-96mb on amd64. |

28 |
But there still might be other things in the jvm that are undesirable |
29 |
performance and etc wise in 1.5.0.x. Which they address in 1.6 or etc. |
