Hi, I just released ltt-control 0.85 which waits for previous subbuffers to be written to disk (using sync_file_range()) and uses fadvise to tell the kernel that pages won't be reaccessed. This lessens the tracer impact on the page cache.
Thanks to Linus for hints on how to use fadvise and sync_file_range to do this, c.f.: http://marc.info/?l=linux-kernel&m=127430576309253&w=2 Mathieu -- Mathieu Desnoyers Operating System Efficiency R&D Consultant EfficiOS Inc. http://www.efficios.com _______________________________________________ ltt-dev mailing list [email protected] http://lists.casi.polymtl.ca/cgi-bin/mailman/listinfo/ltt-dev
