I made a footnote indicating that.
That means that Alto's assigned CPU cores number is the same, otherwise UnixBench would give other results.
Unfortunately, I have canceled a VPS from them prior to running all the tests.
If they would allow me to have that VPS for a day, the results will appear really soon.
If they won't (and they are not obliged to give it for free). well, I'll order one several weeks later and run tests.Last edited by Master Bo; 05-05-2012 at 12:04 AM. Reason: merging responses

Konstantin... can you just verify that what I read is correct about CleverKite CPU is 4x E31270? I just find that an unusual setup...

Those are 'virtual cores', reported by UnixBench.
If I perform 'cat /proc/cpuinfo', I'll see this
Code:... vendor_id : GenuineIntel cpu family : 6 model : 42 model name : Intel(R) Xeon(R) CPU E31270 @ 3.40GHz stepping : 7 cpu MHz : 3392.298 cache size : 8192 KB physical id : 0 siblings : 8 core id : 3 cpu cores : 4 ...

Thanks for making this list. I think we're about to start seeing a faster rise in popularity for this as the VPS market continues growing and disk I/O continues to be on top of the most frequent bottlenecks for the lower price range.
Ain't here to spam my signature, I'm not desperate for sales.

Update: I have also added
Amazon EC2 benchmarks chart
You can also download from that page a .ZIP containing all the benchmarks data.
Yes, there are more and more SSD hosting offers nowadays. I suppose this moment is the rise of this industry. Let's observe and participate.███ IT blog is under reconstruction, please standby

TWIMC, I also am doing the benchmarking of other cloud-based hosting facilities, such as GreenQloud, RackspaceCloud, GigenetCloud, NephoScale, VPS.NET, VPSFarm... name ye cloud, I'll test it.
Stay tuned, there will be announces on VPSeer.Last edited by Master Bo; 05-09-2012 at 01:35 AM.

I couldn't tell you where you've gone wrong but your IOPS values are off by more than an order of magnitude. If I look at your website EC2 data, you list IOPS at 900/1400 for a micro. The actual value is widely measured to peak around 100 IOPS.

There's nothing better than an experiment.
I have built fio tool and ran the IOPS checks on my *busy* t1.micro instance (it means it's not idle as those I used to collect EC2 benchmarks).
The results of several runs of fio (the same parameters I used in the benchmarking):
IOPS random read:
read : io=29656KB, bw=2953.6KB/s, iops=738 , runt= 10041msec
read : io=52892KB, bw=5259.3KB/s, iops=1314 , runt= 10057msec
read : io=76332KB, bw=7598.3KB/s, iops=1899 , runt= 10046msec
read : io=94128KB, bw=9350.2KB/s, iops=2337 , runt= 10067msec
The results then vary, but do not get below 738 or higher than 2500
IOPS random write:
write: io=74012KB, bw=7388.7KB/s, iops=1847 , runt= 10017msec
write: io=72428KB, bw=7229.9KB/s, iops=1807 , runt= 10018msec
write: io=73492KB, bw=7337.5KB/s, iops=1834 , runt= 10016msec
write: io=72076KB, bw=7195.4KB/s, iops=1798 , runt= 10017msec
and so on - they are around 1800
I start to think my measurements were too pessimistic in the chart I posted. IOPS for Amazon EC2 might be significantly better than I obtained in the first tests.
The t1.micro I used is being run for many months and I do not plan to stop it in the foreseeable future. The tests can be re-run whenever required.
Any objections?Last edited by Master Bo; 05-09-2012 at 07:35 PM. Reason: typos

Yes Konstantin... it must be all 4 cores avaliable in the E3 1270 (4 cores chip) which means all CleverKite offerings have access to all 4 cores? on a Single E3 1270 with RAID10 4x SSD's

What are the peak tps reported by "iostat 1 " in a separate window while your tool is running?

Since both fio and iozone perform massive I/O operations, this is what transfers per second (tps) indicate.
That's expected.███ IT blog is under reconstruction, please standby

I'm asking you, what iostat tells you are the tps while you are running fio/iozone. I cannot get a single EBS volume on a Micro to give me more than around 90 IOPS. So since you are reporting a number more than 10X higher than that, I'm trying to reconcile our methodologies. Mine is to saturate the system with IOPS which are reported in iostat and max at around 90. I'm skeptical of the values reported by your tool in this test, but iostat should be accurate.

I'll check what iostat shows while fio/iozone are running.
However, fio seems very popular tool and the command line used is quite typical.
Ever tried to repeat the measurements by running exactly what I did?
Update: OK, I ran the fio tests on my t1.micro, while keeping 'iostat 1' on the same server.
When writing test files, tps was circa 450. When running tests, it burst up to 5700 tps for the first 2-3 seconds and after that gradually diminished to zero, as tests were over.Last edited by Master Bo; 05-10-2012 at 10:38 PM. Reason: tests update added/typos removed

I made a new instance and with iozone I was able to generate 250-300 Iops on a single volume. Seems this has improved quite a lot!

Just to throw it out there, we've modified our offer, and I think we're going to really impress you. Do you sign up 'secretively' or do you use freebies that hosts gave you? It might not be fair if you use a freebie, as they could put you on your own server, and you would never know...

I like being impressed. No, really.
As for SSD VPSes... Three of them (CleverKite, Avante Hosting, VirtualSRV) offered their VPSes for tesing purposes. In all the other cases I buy the services. When there are trial offers, I use trials etc., if they are the same regular plans, just at different pricing.
By the way, I use the same real name/address in all the cases, I see no sense to hide my identity. After all, anyone can run benchmarks, that's not against ToS of the hosters I met so far.
We can ask the mentioned hosters whether their VPSes were regular, created on the same nodes the next paid VPSes would be hosted at.
I see no real sense in offering me VPSes created on empty nodes. Anyone, as I have said, can re-run the benchmarks and if there's significant difference, it will be obvious something is wrong.
I prefer to trust people unless there's a very solid reason to do otherwise.

TWIMC: commencing tests and getting the first impressions of HP Cloud Services (moved to public Beta state two days ago).
Also, if someone wishes to have, sooner rather than later, benchmarks/reviews of certain cloud services I have experience of, please navigate to the lists at the bottom of "I recommend" page and let me know what one.
Now let's see what HP hides in their cloud...███ IT blog is under reconstruction, please standby
