Even though we copy large amounts of memory around, very little time seems to be used in the process. My current test version, with COW strings and a few other tweaks, achieves: 5000 generations in 80.735562 seconds. 61.930578 generations/sec A total of 32768 bytes were allocated A total of 117851 DOD runs were made A total of 333 collection runs were made Copying a total of 1347808 bytes compared to a current CVS version of: 5000 generations in 90.813806 seconds. 55.057708 generations/sec A total of 32768 bytes were allocated A total of 130932 DOD runs were made A total of 10930 collection runs were made Copying a total of 57801936 bytes so a 97% decrease in the number of collection runs only turns into an 11% improvement in total performance.
