Bandwidth Testing part 2

Continued on with my bandwidth testing, these are the results after having restarted the cable modem (which supposedly updated its firmware) as instructed by my ISP's support folks. Below are the results:



And below the results from Speedtest.net whom btw make use of the same software but a different server infrastructure I'm sure. The interesting thing is that their results are actually better than those measured solely on Telenet's network (although only marginally so).


The above results are measured on an Asus EEE PC 900 (with built-in wifi of the 802.11b/g denomination).

The results below here are measured on a Macbook running Mac OS X 10.5.6 and a built-in Airport Extreme of the 802.11n (draft) denomination...



And again using the ISP's meter:


Ok so clearly the Asus EEE PC 900's wifi is the bottleneck in these tests and the Macbook is able to use bandwidth all the way up to the ISP's limits...

I wonder if my abhorrent download results earlier were a function of limits at the server I was downloading from or if there was something else limiting going on... hard to troubleshoot these transient type issues.

Anyhow, back to report these results to the support folks @ my ISP....

To be continued....

Bandwidth Testing

I have been experiencing strange delays with my Internet download speeds lately that have started to bug me so much that I decided to report the issue to my ISP and see if they are able to help resolve this.

I have a so called Turbonet subscription which entitles me (according to Telenet's) latest being adertized on their website to 25Mbps download speed. Originally was sold to me as 20Mbps tho.

The main thing I've noticed is download speeds have become irratic and slow at times.

It so happens that a little while go a started measuring my dl speeds and at first I got this:


The download seems fairly close to what is to be expected, the upload speed tho seems only half of what is to be expected.

The second measurement (which was actually earlier this evening (on a Windows 7 machine):



This shows less then half of what its supposed to be...

I then later did a second test from my Ubuntu Netbook and got the following result:



Very similar to the results earlier from the Windows machine so I'm ruling out any computer related problems.

Finally the result from my ISP's bandwidth meter:


So there my upload speed dropped again, otherwise its close to the other 2 results of this evening.

Now I'm supposed to reset my router, which I will do tomorrow. This reset is supposed to load the router with its latest firmware according to my ISP.

I'll retest tomorrow, to be continued....

Advances in Virtualization

I have been reading various interesting articles on various blogs n vendor websites about the oncoming onslaught of new technologies in the virtualization hard and software space. A lot of the software side was revealed by virtualization leader VMware during VMworld Europe and on top of that we get Cisco's announcement around their UCS offering.
An interesting dicussion by Scott Lowe, about some of the technologies involved can be found here. It is indeed more profound then Cisco simply entering the bladeserver market.
It's essentially the birth of a next-gen virtualization eco-system that takes virtualization to the next level. Of course we're only just standing at the virtual craddle of this new baby, but given how the various developments are coalescing, it's quite clear that this may in fact be a new-wave of virtualization, in bringing the infrastructure for Compute, Storage and network to new optimal performance levels, while promising to ease the burden of management. Now we see how the traditional server vendors react...
