Prices seem really great but a few paragraphs down they say the servers are based on Avoton SoCs. Intel Avoton is an Atom chip (Silvermont core), so CPU-bound performance will be somewhat lower than the usual Sandy Bridge/Haswell/whatever core that you get on AWS or Google Compute Engine. It's a server SoC though so I/O throughput is probably pretty decent...

That's what scares me a bit. The multi-core performance is great (considering their pricing), but single-threaded performance is quite a bit below what the competition gets you. If you're running a web server with something single-threaded (like PHP) requests might start taking a bit longer than you're used to.

How much time are you spending in php per request? I would think the time spent in PHP per request would be low compared to network latency and io.

Correct me if I'm wrong but you can spin up multiple PHP worker processes to take advantage of those cores?

That means you can process more requests at once (across several threads/cores), but per request timings will be slower because each core is slower than the cores on the competitions CPUs.

Can confirm. Dual core Atom loading bare Wordpress is a nightmare without caching, and still barely acceptable with caching.

How does the CPU performance of Avoton compare to a Pi 2? How do they perform on single threaded encryption, eg for a Tor relay?

I can't actually test it, but considering nbench shows the Avoton is faster on regular CPU operations, and that on top of that it comes with native AES-NI support (unlike the ARM CPU used by the Pi), it's probably much faster at Tor encryption.

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

Please run nbench [1]. I ran it on the C1 in April 2015 and got the following results: CPU : 4 CPU L2 Cache : OS : Linux 3.2.34-29 C compiler : gcc version 4.8.2 (Ubuntu/Linaro 4.8.2-19ubuntu1) libc : libc-2.19.so MEMORY INDEX : 5.859 INTEGER INDEX : 8.164 FLOATING-POINT INDEX: 5.770 For comparison, here are an Intel Atom N450, a Core 2 Duo L7500 and a Raspberry Pi 1 Model B: CPU : Dual GenuineIntel Intel(R) Atom(TM)…

How "reliable" are those numbers in estimating real application performance?

I've run nbench for a 1 CPU VM in EC2, and a 2 CPU VM in DO, and the former is a lot faster ( almost 2x ) than the latter!

Here are the results on a C2S: CPU : 4 CPU GenuineIntel Intel(R) Atom(TM) CPU C2550 @ 2.40GHz 2394MHz L2 Cache : 1024 KB OS : Linux 4.4.4-std-3 C compiler : gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.1) libc : libc-2.19.so MEMORY INDEX : 22.134 INTEGER INDEX : 17.899 FLOATING-POINT INDEX: 21.522

I have to be honest, they don't look bad at all.

From my experience so far, C1 is like working with a microwave, and VC1 (VPS) is much nicer, for €2.99 let's not forget.

More results for comparison: http://www.tux.org/~mayer/linux/results2.html Looks like it's around the speed of a 1GHz Pentium III.

But what about the VC1 (VPS)?

I have a 3€ C1 server at Scaleway moving some 25-30TB of data per month, so yes, it's very real.

amazing! very good!

With my tor relays I pushed around 150Mbit up and Down. Which is around 45TB per direction and Month.

I think I have a number of invites, but the site is very slow at the moment.

if you have one more invite, i've sent you an email with request :) thx

Invitations won't get too far : "Send an invitation to your friend to try Scaleway! Your invitation will get queued and sent when enough capacity is available."

unlimited bandwidth. Is that for real? 300 Mbits. Let's assume you can pump out 100 Mbit sustained. That is about 10 MB/s. or 26,000,000 Megabytes/month. 26,000 GB / month. AWS & google cloud are about $.10/GB. That'd cost 2600 USD to serve. Scaleway claims that'd cost just 12 euro. For realz?

"unmetered" is a popular dedicated hosting company marketing trick. things are generally oversubscribed to horrifically oversubscribed and you'll be very hard pressed to sustain 100Mbps 24x7 for a full day, let alone a full month.

I pushed on 2 instances around 150Mbit/s with no problems at all :)
