Stupid Benchmark Thread

I’m gunna be benchmarking a bunch of stupd stuff soon. I encourage yall to do so as well.

GB5 gives test totals o.o thats super cool

It is not stupid, but a bit anecdotal. I benchmarked the linux versus the linux-hardened kernel on my laptop.

linux:

Benchmark Summary
  Single-Core Score              990
    Crypto Score                  1218
    Integer Score                  931
    Floating Point Score          1081
  Multi-Core Score              3732
    Crypto Score                  4814
    Integer Score                 3532
    Floating Point Score          3984

linux-hardened

25% performance penalty in multicore scenarios.

I mean thats just plain fascinating

I want to add that the CPU is a i7-6700HQ. So a penalty like this was to be expected since, when being pedantic about security, you have to mitigate quite some vulnerabilities on an Intel CPU like this. The linux-hardened kernel deactivates HT for example, as far as I am aware. This alone should have an significant impact. I am now interested to see how my HP Compaq 6910p with a Core 2 Duo T7100 holds up, since it should lack many of the security compromising and performance enhancing developments that have been made in chip design in the meantime.

The OG stupid benchmark: bogomips.

My Ryzen 5 5600X clocks in at 7386.02 bogomips. Be impressed.
