Hi,
Is it reasonable for a 64bit dual cpu to take 5+ seconds of processing to cat /proc/*/statm when there is hardly more than 1gb of actual memory space used by processes (the rest being filesystem cache)?
This makes top or anything else that uses statm, unusable.
I don't observe this behavior on a 4gb 32bit machine, with the same working set of mysqld processes, and 3gb of filesystem cache.
