The benefits are superior control of the memory footprint, reduced code fragmentation, and improved iTLB/iCache behavior because of enhanced locality. iTLB/iCache is a CPU-precise expression this means Instruction Translation Lookaside Buffer (ITLB). ICache is definitely an instruction cache in theCPU. The implementation of your code cache can be found from the file: /share/vm/code/codeCache.cpp.

) Also, for evenly contended locks that happen to be employed by various threads, RTM can minimize Fake cache line sharing, often called cache line ping-pong. This happens when a number of threads from diverse processors are accessing distinctive assets, although the means share precisely the same cache line.
