Reviewing a 6GB RAM VPS from TNAHosting

- Posted in VPS by with comments

Today I will be looking at a VPS that falls in 2 categories - storage VPS and high RAM VPS.

Here's a deal from TNAHosting:

  • 6GB OpenVZ - Chicago, IL
  • 1 IPv4 [IPv6 available]
  • 2x vCPU
  • 200GB HDD
  • 2TB Bandwidth
  • $5/m - Order Here

200GB HDD with 6GB RAM and 2 cores is a pretty sweet deal for $5 per month. Let's see what it looks like under pressure..

CPU model:  Intel(R) Xeon(R) CPU           L5420  @ 2.50GHz
Number of cores: 2
CPU frequency:  2500.020 MHz
Total amount of RAM: 6144 MB
Total amount of swap:  MB
I/O speed:  434 MB/s
Bzip 25MB: 5.88s

Total amount of RAM: 6144 MB
Total amount of swap:  MB
I/O speed:  483 MB/s

CPU model:  Intel(R) Xeon(R) CPU           L5420  @ 2.50GHz

Total amount of swap:  MB 
I/O speed:  506 MB/s
Bzip 25MB: 5.87s

We're getting 2x 2.5ghz Xeon cores and 6GB of RAM, no swap (but with 6GB of RAM why would you want to swap it to HDD?) The I/O speed is impressive, it could be cached by the looks of it, but that's a very good result! And the CPU is fast! Navigating the system through SSH feels very responsive and things happen quickly.

Here's a different perspective:

Disk access is incredibly fast on this VPS, this looks like the perfect VPS for Plex Media Server!

A good test is to see how well Plex can transcode a 1080 movie and stream it to me here in Australia - not all providers can achieve this due to CPU/RAM restraints or network issues. This VPS, being in Chicago, by default doesn't have a great connection to the Asia/Pacific region, which is true for most providers.

I have installed Plex and can happily report that I was able to successfully transcode and stream a 1080 movie to my place in Australia. This VPS is excellent value for the price, I highly recommend it to anyone who needs a VPS to do more than just idle away!

From what I understand, there is limited stock on this so take action now and order it if you're looking for a good VPS.

I have also added this to my Storage VPS list.

Benchmarking a time4vps storage VPS

- Posted in VPS by with comments

Time4vps have been providing high storage VPS for a while now, and they're one of the popular providers for storage.

Here's an offer from them in their datacenter in Lithuania, Europe.

  • 1x1.7ghz processor
  • 1GB RAM
  • 1TB HDD (RAID, 200IOPS limit)
  • 10TB bandwidth
  • 100mbit network
  • OpenVZ
  • Hosted in Lithuania, Europe.
  • 5.99 EUR/month

This looks like a good storage deal for the price, there's plenty of bandwidth too. The 200 IO/s is an interesting limit, meaning 200 I/O operations per second. Let's see what it looks like with a benchmark script:

CPU model:  Intel(R) Xeon(R) CPU E5-2603 v4 @ 1.70GHz
Number of cores: 1
CPU frequency:  1698.052 MHz
Total amount of RAM: 1024 MB
Total amount of swap: 512 MB
I/O speed:  66.4 MB/s
Bzip 25MB: 6.85s
Download 100MB file: 11.4MB/s

That's not too bad, the CPU seems to be fairly available and the 100mbit connection capped out.

Here's more..

Total amount of swap: 512 MB
I/O speed:  65.9 MB/s

I think the IOPS cap is coming into play here, being a storage server it's probably a good thing to avoid noisy neighbours from making the disk unstably slow.

It runs nextCloud fine, although a little slow when loading pages, it's not as snappy as some other providers. The fact that it's openVZ really, in my opinion, disqualifies it from being useful to me (I love KVM and encrypted LVM volumes for my private data)

If you need cheap storage, consider this offer from time4vps.

I came across this cheap NAT KVM Storage offer from wishosting recently and I thought I would do some benchmarks on it to see how it performs. Here's the deal:

  • 1 vCPU core i7-3770
  • Unlimited CPU core 3.7GHz Turbo
  • 1GB RAM
  • 1TB HDD RAID-5
  • Linux/Windows OS
  • Bandwidth 250Mbps
  • Traffic 2TB
  • 1 IPv4 NAT
  • DDoS protection
  • Location - Germany
  • Setup time up to 24 hours
  • $4.99/month (paid quarterly)
  • $5.00 one off for a dedicated IPv4

I decided to make my life a little easier and got the IPv4 upgrade. The KVM is in Germany, and the IPv4 is in France, it does some crazy proxy trickery but it works perfectly! A couple of hours later, Michael from wishosting had my account set up and even helped with some questions I had. I must say, he's very professional in his ticket etiquette!

Here's some benchmarks:

CPU model:  Intel Xeon E312xx (Sandy Bridge)
Number of cores: 1
CPU frequency:  3399.998 MHz
Total amount of RAM: 988 MB
Total amount of swap:  MB

Bzip 25MB: 4.12s

This is a very speedy KVM service! It feels very snappy, sometimes servers feel a little slow but this feels like I'm the only user on the node which is amazing! I would definitely recommend this to anyone looking for a great value KVM with 1TB of storage!

After falling in love with the other V-Dedi from WISHOSTING, I decide to test out another one. This time it's an Intel Avoton C2750-based box.

Here's the features:

8 CPU cores Avoton C2750
Dedicated CPU cores 2.4GHZ
7GB RAM
800GB HDD
Linux/Windows OS
Unmetered traffic
Best effort 1 Gbps bandwidth
1 IPv4
Location - France
Setup time up to 24 hours
[$14.99/month][2]

The differences between this package and the other one is this is $5 per month cheaper, has gigabit instead of 100mbit, but we trade off with an 800GB HDD instead of 1.8TB HDD and 7GB RAM instead of 15GB RAM. The big thing that I noticed is the 4 extra cores - 8 in total. I just had to benchmark this and see how it performs.

And here's some benchmarks which I will add to later:

CPU model:  Westmere E56xx/L56xx/X56xx (Nehalem-C)
Number of cores: 8
CPU frequency:  2399.998 MHz
Total amount of RAM: 6971 MB
Total amount of swap:  MB
System uptime:   7 min,       
I/O speed:  252 MB/s
Bzip 25MB: 12.49s
Download 100MB file: 96.1MB/s
CPU model:  Westmere E56xx/L56xx/X56xx (Nehalem-C)
Number of cores: 8
CPU frequency:  2399.998 MHz
Total amount of RAM: 6971 MB
Total amount of swap:  MB
System uptime:   5 days, 19:32,       
I/O speed:  43.7 MB/s
Bzip 25MB: 13.57s
Download 100MB file: 87.8MB/s

The Bzip time is almost 4 times higher, meaning it look 4 times longer than the i5 based system - expected behaviour for an Atom processor. The I/O is great and the network is gigabit, which we can see from the results.

It's a great deal, but the other package I have looks better for the extra storage and RAM. I will set this up for a month with nextCloud and Plex and see how well it handles those tasks. At this stage, I can't see it replacing the other V-Dedi from WISHOSTING.

Stay tuned, I'll update this as I go along.

UPDATE: So I've had this for close to a week now and I've been testing it, and it's a very capable dedi for the price. It's nice seeing the 8 cores in htop. I admit, I am struggling to find something else to love about this. Compared to the i5 server they have on offer, which is much noticeably faster than this atom server, coupled with the 1TB loss in storage, I feel like this server wouldn't suit my needs. Also, the extra 100ms in latency did give me some issues streaming plex during peak times, but that's what happens when it's 300+ms from France to Sydney.

Benchmarking a Linux machine

- Posted in Quick Tip by with comments

When I'm playing with a new VPS, the first thing I like to do is run a benchmark to see if I've got a good deal.

Running this in a terminal will start the benchmark (only need to install time and bzip2 once)

apt-get install time bzip2
bash <(wget --no-check-certificate -O - https://raw.github.com/mgutz/vpsbench/master/vpsbench)

You'll get an output similar to this

CPU model:  Intel(R) Xeon(R) CPU E5-2609 v3 @ 1.90GHz
Number of cores: 1
CPU frequency:  1897.804 MHz
Total amount of RAM: 1024 MB
Total amount of swap:  MB
System uptime:   6 min,       
I/O speed:  58.2 MB/s
Bzip 25MB: 6.76s
Download 100MB file: 34.2MB/s

Just got this new toy, off to play with it ;)
