Currently Linux is used in enterprise systems which require low latency (e.g. few msec/transaction). In such systems, latency of memory allocation/access is really important. To satisfy customers latency requirement, commercial Unix has pagecache limitation features. But Linux doesn't have it and has been improved to reduce latency without it. This talk will cover the efforts which were done in the community, their evaluation and discussion for future improvement. The target audience is system administrators and developers who are interested in system latency.
