Microbench aims at comparing STM performance against performance of lock-based and lock-free alternatives. It comprises common data structures: linked list, skip list, hashtable… Microbench derives from the stm-based linked list test of TinySTM and the current release includes the SUN stm-based red-black tree benchmark. It also features fine-grained locking algorithms (e.g., lazy linked list, optimistic skip list) and lock-free algorithms (e.g., harris-michael, fraser's lock-free skip-list).
