Thanx for posting this info. The cpuinfo matches Marvell Armada XP.

#13Something that has hopefully not been overlooked for the paid version - making sure there is an ability to restart from the control panel (or whatever) - after issuing the shutdown command as root I thought refreshing the page might attempt to bring it back up but alas I was locked out for the rest of the 15 minutes.

Not a scientific measure by ANY measure, but a similar core I googled appears to kick out about 200 bogomips whereas a virtual Xeon E5-2690 v2 core on one of my machines knocks out 5984 bogomips. I have 20 of those Xeon cores and 128Gb of RAM in a 2U. Comparing the ratio of bogomips you'd have to get 598 of those ARM machines in a 2U to get the same bogomips. Like I said this isn't even slightly scientific but is at…
Thanks for the trivia. Just to continue on this path, how many virtualized instances can you put on your machine ?
Not tried to push it but it has 20 Windows Server 2012 R2 instances running on it at the moment all with 8Gb of memory (this is overcommitted dynamic memory). Disk is on a SAN larger than my kitchen. I span up a Linux VM quickly to do a bogomips on :)
I can probably push 40 of those onto it without it bending too terribly. If I knock the RAM down to 2Gb an instance I could probably quite happily get 64-100 on it in theory. I think memory bandwidth might kill it before CPU does.
We have two almost full (18 each) 42U racks of those machines (bar switches) so across the 720 E5 cores with 4.6TiB of RAM there is about 4.3 million bogomips.
Fun :)
(most of this is corporate fileservers, exchange, AD, various crappy apps, network appliances, web servers, SQL servers and idles at around 20% in use). If it all went off you'd need earplugs and fireman's equipment.

#15> Follow @online_en on Twitter and send us a direct message with your email. Don't they have to follow YOU to be able to do that?
Yes. They won't be getting anybody sending them a direct message.

Not that it'd cover for the difference but note that you're only using one of the 4 threads of the C1. If I'm not mistaken you only have 1 CPU for a droplet at this price.
The Arm cores are also dedicated while the one on digital ocean is shared.

dmesg output mentions Armada XP pinctrl and xor engine too.

#20Nice option, how much compute power does these ARM servers offer though?

I found other source where they said it's around 1200 bogomips for a single core. That would means that you only need 5 times more core which is far from being an issue, 100 cores, which means only 25 processors.
