There's a good posting from May 2015 by Martin Rusev comparing Scaleway and DigitalOcean that includes a benchmark. This post adds results from Raspberry Pi 2 and an older Intel i3 system of mine with Ubuntu.
The commands used for single and multi-threading were:
sysbench --test=cpu --cpu-max-prime=20000 run sysbench --test=cpu --cpu-max-prime=20000 run --num-threads=4
DigitalOcean: 42.4121s Scaleway: 685.5120s (16x slower) Pi 2: 1143.0230s (27x slower) i3 3120M 2.5Ghz: 33.76s (ZBox ID83, Dual Core)
DigitalOcean: 21.3409s Scaleway: 171.3962s (8x slower) Pi 2: 290.7834s (13.6x slower) i3 3120M 2.5Ghz: 9.94s (ZBox ID83, Dual Core)
The commands used were:
sysbench --test=fileio --file-total-size=6G prepare sysbench --test=fileio --file-total-size=6G --file-test-mode=rndrw --max-time=300 --max-requests=0 --file-extra-flags=direct run sysbench --test=fileio --file-total-size=6G cleanup
DigitalOcean: 54.565Mb/sec Scaleway: 16.347Mb/sec (3.33x slower) Pi 2: .054Mb/sec (1,000x slower)
The disk I/O seems so much slower on the Pi that it's hard to believe. I'm using a 32Gb Samsung Class 10 Micro SDHC card. I'll have to try this test on another card.
