That's about 20GB on a 32GB Mac, OSX 10.9 Mountaineer
I remember one time you told me it doesn't make as big a difference manually adjusting the memory in OSX like it does in Windows.
I don't know a lot about memory allocation on a Mac. I have received warnings that my Startup disc was full due to the Virtual Memory allocation. I'm guessing it must be like a pagefile in Windows? So having an SSD for a startup OSX disc does make a difference with Songkong when storing the input file there.That I know from personal experience.
Do you think implementing a percentage heap file value in OSX, similar to what was done in Windows would be helpful? Also would increasing the real memory and/or private memory improve performance and reduce the virtual memory size requirement? If it's like a RAMDISK put into memory, probably would not make a difference, I'm guessing. if it's paging to disk then it would probably help?
Finally with Java 8, are there any new tuning parameters coming that may help Songkong performance?
Apologize for all of the questions but they are somewhat related
