How do you figure? Unless recent versions of Whisper have been totally rewritten, whisper writes each metric to a separate file. Submit hundreds of metric per vm/server every 10 seconds, and you get ridiculous amounts of tiny writes (e.g. 4 byte writes) fenced by redundant seek()'s and a number of other syscalls, no matter how much you batch up stuff before sending it to statsd. |
