Append the letter k or K to point kilobytes, m or M to point megabytes, g or G to point gigabytes. The following illustrations demonstrate ways to set the scale of allocated memory to 6 MB working with many models:

Instructs not to print the compile commands. By default, the commands that you specify with the -XX:CompileCommand alternative are printed; for example, should you exclude from compilation the indexOf() technique of the String class, then the subsequent is printed to standard output:

Adverse values denote that prefetch distance is picked out based upon the platform. Constructive values are bytes to prefetch. Append the letter k or K to indicate kilobytes, m or M to indicate megabytes, why not try this out or g or G to indicate gigabytes. The default benefit is ready to -one.
