<edit>Genau 50% hört sich danach an das nur eine CPU genutzt wird. Ich bermute die Simulation benutzt nur einen Thread.</edit>
AFAIK beschränkt die JVM standardmäßig den Speicher auf 64MB . Vielleicht liegt's ja daran:
Zitat:
-Xmsn
Specify the initial size, in bytes, of the memory allocation pool. This value must be a multiple of 1024 greater than 1MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 2MB. Examples:
-Xms6291456
-Xms6144k
-Xms6m
-Xmxn Specify the maximum size, in bytes, of the memory allocation pool. This value must a multiple of 1024 greater than 2MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 64MB. Examples:
-Xmx83886080
-Xmx81920k
-Xmx80m
