The `current-process-milliseconds' function returns a thread-specific value if you give it a thread argument. > 2) Memory usages > > Also memory usages per each thread in rum-time?? > As I know Linux doesn't provide the way to measure memory usage per each > thread. > So How about Racket? You can't ask for thread-specific memory use directly, but you can ask for custodian-specific memory use, and every thread can have its own custodian. Beware of sharing among threads and how that influences memory accounting. For more information about custodian-based memory accounting, see "Memory Accounting without Partitions" Wick and Flatt, ISMM'04 http://dl.acm.org/authorize?730730 Addendum: http://www.cs.utah.edu/plt/publications/ismm04-addendum.txt ____________________ Racket Users list: http://lists.racket-lang.org/users
