I compared the run time of the test program of SRFI 231, an array SRFI:

https://srfi.schemers.org/srfi-231/

by upping the number of samples in each random test to 10,000 by setting random-tests to 10000 in

I used the same version of Gambit and gcc on all machines:

lucier% gsi -v v4.9.4-26-g015c8875 20220323161655 x86_64-apple-darwin20.6.0 "./configure 'CC=/usr/local/gcc-11.2.0/bin/gcc' '--enable-march=native' '--enable-dynamic-clib' '--enable-single-host' '--enable-multiple-versions' '--enable-shared’”

The results:

Dell Workstation running Ubuntu 20.04

model name : Intel(R) Xeon(R) CPU E3-1271 v3 @ 3.60GHz 144.279u 0.443s 2:25.12 99.7% 0+0k 8+1024io 0pf+0w 32GB RAM

Model Identifier: MacBookPro18,4 Chip: Apple M1 Max Up to 3.228 GHz 64GB RAM 69.523u 0.324s 1:10.25 99.4% 0+0k 0+0io 0pf+0w

Model Identifier: Macmini8,1 Processor Name: 6-Core Intel Core i7 Processor Speed: 3.2 GHz Intel Core i7-8700B @ 3.2 GHz 107.773u 0.255s 1:48.65 99.4% 0+0k 0+0io 0pf+0w

So running this, the Mac mini is significantly faster than the Linux box, but the Linux box feels faster for nearly all development.

I’m quite pleased with the MacBook Pro, though.
