Abstract
I also provide an analysis of I/O in lock-based critical sections in large multithreaded workloads, with observations on how this I/O could be performed in transactional code. In this analysis, I find that no one of the previously proposed techniques is by itself sufficient for handling side-effects without sacrificing performance. However, I conclude that the majority of transactional I/O is likely to be compensatable, and that causing transactions performing I/O to 'go nonspeculative' can be a reasonable choice for uncompensated I/O, provided that it does not delay non-side effecting transactions.
