Nearly no web framework is per request multi core (e.g. multi core HTML / JSON rendering, assuming backend operations already async). So each request will be slow. [Edit:] Not sure for the downvote, would be interested what's wrong in my comment.
Go's net/http framework uses a go routine per connection.

If nbench only uses 1 core, yes, my comparison is wrong. Is there a similar benchmarking linux tool that can use many cores? edit: instance is a t2.micro
I don't think the comparison is wrong per se; this actually makes it a bit easier, since you're just comparing one core to another. The only thing that I think is problematic is comparing a t2 to anything else, since that CPU performance is not sustainable as it might be elsewhere. m3 and m4 (and other instance types @ aws) are not explicitly throttled.

I'm happy to run any benchmarks people like (within reason). I can also compare to most AWS instances if you like.

If you do CPU-intensive work on these servers, might not the electricity cost surpass the 0.02/hour income? Example: if a kWh costs 0.10, then to have something burning 200W costs 0.02 per hour. (Someone substitute real-ish numbers.)

> I doubt that Just tried for a few minutes all 3 of them. The C2S is a C2550, and the C2M and C2L are C2750. They each appear to be bare metal, and not virtualized. The VPS offering, which is advertised as a VPS, appears to be virtualized inside of a C2750. The C1 is a Marvell Armada 370/XP, a bare metal ARMv7l board. > I would consider their offers "ad-supported". This also is not my experience. I haven't ever rece…
> They each appear to be bare metal, and not virtualized How can you tell?
* loaded drivers may be named after the virtualization platform (VMware)
* CPUs can be reported as "Virtual" in /proc/cpuinfo
* Special files in /proc (for instance "vz" for OVZ)
* Kernel name
* etc.
Avotons are very slow, an 8C SoC will typically be slower than an 8 year old 2C desktop CPU (I ran Go builds as a benchmark on my own 2.4 GHz C2750 vs. a 2008 iMac with 2.8 GHz Core 2 Duo). As for Scaleway, some people seem to like it very much, but I found their policy about spamming their users problematic. They (online.net) mock you at registration with a sleazy checked and disabled box for receiving spam ("produc…
