  1. Cool! Very informative, thank you!

    I’d like to point out (what i think is) a small typo:
    “…
    At least the Python 3 version seems to fill up the pipeline nicely (1.1 instructions per second), compared to Python 2 (less than 1 instruction per second).
    …”

    I think you meant: “instructions per *cycle* ” in both cases, yes?

    Hi! Thanks allot for that!
    Do you happen to know how can I use perf to get a graph of some event as a function of time?
    Say, y-axis is the CPI and x-axis is cycles.

    Any help would be appreciated!

  3. I had a feeling something weird was going on when my Java program was slower than my python version, despite Java being compiled and python being interpreted. Thanks for the informative article.

      Java is not compiled into processor native language but, instead, it is compiled into an intermediary language (Java ByteCode) which will eventually get interpreted using JVM.
