Wait, what's the CPU frequency on Scaleway?

I just created a test instance with them and ran an open source project of mine. It runs just as fast as anywhere else, but compiling it takes 5 times as long. Investigating further to see if it's just something about my (weird) project.

Edit: ah pella posted a comment at the same time as me with details on just how slow the ARM CPU is: https://news.ycombinator.com/item?id=10161307. The benchmarks linked there are 15x slower on single-threaded workloads.

One thing with those benchmarks:

Amon's piece is back when Scaleway was way more expensive. Amon says that he started a DigitalOcean Droplet with similar specs to the Scaleway box.

The Scaleway box has 2GB of memeory and 4 cores.

The first Digital Ocean box with more than 1 core and 2GB of memory is $20 a month. That's 6 times more expensive than Scaleway!

It would be interesting to see what the benchmarks would be like on the price competitive Digital Ocean offering (single core, 512MB memory, 20GB Hard disk)

I just tried it and got a 20x difference.

Scaleway, using one of four 1332 bogomips processors and 2GB RAM (~$3.30/mo):

  Test execution summary:
      total time:                          685.4730s

Digital Ocean, using the sole 4600 bogomips processor and 512MB RAM ($5/mo):

  Test execution summary:
      total time:                          34.9343s

           max:                                  8.00ms
           approx.  95 percentile:               3.68ms

Commandline:

  $ sysbench --test=cpu --cpu-max-prime=20000 run

Ouch! That is a very big deal.
