osx snow leopard - java caching files across multiple runs of the same application -


i trying generate data use in report. issue first time run program data set, takes longer process data. rest of times run program data set quicker half time. problem need duplicate results of first run each time. because in reality user never load data set multiple times in row. question how can make java stop caching these files across multiple runs. or mac doing me. also, other way me duplicate first run results restart machine, , not want each time want run test. ideas appriciated.

java's not caching files, operating system is.

i assume you're working on performance (or else why care?). create many copies of data , load different 1 each time.
