Robin, 1) it must be debug build of drlvm; 2) syntax is -Xstats:[1|2|3] , the number denotes detalization level.
Actually this options gives various *statistics* for run, rather than performance data or profile. E.g. number of particular byte ops performed, exceptions thrown/caugth, most frequently allocated classes, usage of internal memory pools, etc. I'm not sure this is what you requested - do you need to tune the VM for best performance or collect additional info during run or smth else? 2006/11/9, Robin Garner <[EMAIL PROTECTED]>:
