[TUHS] benchmark

[Clem Cole via TUHS]

The SPEC suite is well regarded and there are many results available on the
main website. However the complete suite costs money. But some parts are
FOSS and available at https://spec.cs.miami.edu/sources/

Larry’s lmbench https://lmbench.sourceforge.net/whatis_lmbench.html Is well
known and a lot more drystone useful than simple things like drystone.

Some others to consider are UnixBench, Bonnie++, foo, iozone. These tools
measure metrics like context switching, process creation, file system
throughput, and data transfer rates.

   - *System & CPU Benchmarks:*
      - *UnixBench:* A classic benchmark for testing CPU, memory, and file
      system performance.
      - *Phoronix Test Suite:* An comprehensive, open-source testing and
      benchmarking platform for Linux and other operating systems.
      - *Hardinfo:* Provides detailed system information and basic
      benchmarks.
      - *Dhrystone/Whetstone:* Tests for integer and floating-point CPU
      performance.
   - *Disk I/O & Filesystem Benchmarks:*
      - *Bonnie++:* Tests file system performance, such as file creation
      and deletion.
      - *IOzone:* Measures filesystem performance across various
      operations, including read/write speeds.
      - *fio:* A flexible tool for stress-testing storage, often used for
      benchmarking SSDs and virtual hardware.
   - *Networking & Other Benchmarks:*
      - *Iperf/Netpipe:* Often used within clusters to measure network
      throughput.
      - *AIM7:* Used to measure the performance of multiuser/shared systems.




One other thought. You might want to try to run whichever suite you pick
against a known baseline of real hardware.  I believe SDF-ICM has Miss
Piggy available again on the Internet. This system is an 11/70 that was the
original development system at Microsoft, but I’m not sure what OS they
have running on it.
