HarborVPS LXC hosting review

VPNrevie.ws -

When you want a step up from shared hosting or wish for more freedom to install your own software (such as a VPN), a VPS can be a solution.
But how do you know if your provider respects your privacy?
Enter HarborVPS: the Canadian-owned Swiss VPS company.


Why Switzerland? Switzerland has one of the strictest privacy set of laws in the world. Situated right in the centre of Europe - yet not part of the European Union - Switzerland is at an ideal place for connectivity, with access to AMS-IX and other important exchanges.


But Swiss VPS offers often have a significant problem: their price. Being an almost exotic location, Swiss virtual private servers often come at a premium.

The Promise

HarborVPS's motto is "Privacy + Performance". The Privacy part is firstly based upon the very location of the servers: Switzerland. It is also linked to the AUP and TOS which allow private VPN services. But what about performance? How does it fare compared to the standards of the industry, namely DigitalOcean and Vultr?

The offer I tested is the smallest and most affordable: Raft at USD 6.95 per month.

It includes 1 vCPU at 3.3Ghz (turbo speed), 512 MB of DDR3 RAM, 256 MB SWAP, 15 GB of RAID SSD storage, and only 500 GB of transfer with 1 IPv4 address.

The Reality

HarborVPS colocate their servers in Zurich at PrivateLayer - which means they own their hardware instead of leasing it. PrivateLayer are well-known in the world of VPNs, as they are the datacenters often used by providers for their Swiss location. Private Internet Access and Speedify both have their Swiss server at PrivateLayer for example.

VPS creation

Signing up to HarborVPS is quite a standard process: as with all WHMCS-powered control panels, you'll be asked to input a domain name for your VPS. While this step could seem weird at first, it is part of the usual signup funnel for this particular platform.

When validating your order, you'll have to create an account in the billing area of HarborVPS.

Payment can be made either with Paypal, pre-paid debit cards or cryptocurrencies.

VPS setup took less than 5 minutes, as it was fully automatic.

You can choose among a limited list of OS templates, which for now include

  • CentOS 7
  • Debian 8 or 9
  • Ubuntu 16.04, 16.10, 17.04 or 17.10

Control Panel

The control panel is Proxmox, which allows for starting/stopping your VPS, reinstalling from a template, and other usual tasks.

One thing to note is that backups are included in the price, a feature seldom present in unmanaged VPS offers. There are both automatic backups and the possibility to make your own; although creating a snapshot erases the previously saved one. Snapshots and backups cannot be downloaded - but you can restore them easily.

The network

Connectivity for a private server is critical: peering and routing differs from provider to provider. This determines the latency your visitors or users will experience between their devices and your server - or your browsing experience if your use the VPS for VPN purposes.

HarborVPS advertise a 10Gbit/s network. This is obviously not the bandwidth dedicated to your particular VPS, but to the hypervisor. In other words, you share this massive bandwidth capacity with other customers whose VPS is on the same physical machine.

Still, you can expect at least over 100 Mbps for the upload speed, and around 500 Mbps for the download part.

Unfortunately, the network is limited to only 500 GB on the smallest plan.

CPU Performance

Unlike with some VPS offers, you won't find old-as-dirt processors straight from the bargain bin, or as it is often the case, the latest ebay decommissioned server lot auction. All HarborVPS's servers are of the SuperMicro brand, with Dual Xeon E5-2670.

Unixbench reports a single-core CPU performance of around 600, which is decidedly average.

Disk Performance

Disk access is fast, but does not seem to be the newer type of SSD: NVMe, which would allow for speeds even greater than SATA 3 can achieve.

About LXC

Virtualisation types for Virtual Private Servers do not come with the same degree of freedom.

The cheapest system is OpenVZ, which you will often find in low-end VPS offers. With OpenVZ, your kernel is shared. As such, this type of virtualisation can offer better performance at the expanse of limited customisation and a shared kernel from the last decade. With OpenVZ, you are stuck with a GNU/Linux kernel from the 2.6 branch.

At the other end of the spectrum, KVM is full virtualisation: you can install whatever OS you want on it, even BSD variants and Windows.

LXC, which stands for Linux Containers is in the middle. An LXC VPS is not exactly a full-fledged Virtual Machine, but allows for more recent kernels than OpenVZ.

One interesting fact is that LXC is actually the precursor to Docker, the now-ubiquitous container format. Yet, trying to install Docker on a LXC VPS will fail, as it would require disabling SELinux on the host machine - which would put the segregation of users' data at risk.

Support

Support is fast and usually replies under an hour. You can raise a ticket in the client area, or use the live chat widget on the homepage.

More surprisingly, support is also available through the Telegram messenger app.

Benchmarks

Here are some benchmarks, executed with a freshly-installed system. ServerScope benchmark was unable to complete because of LXC-related errors.
