I’d like to wish everyone a Merry Christmas and a Happy New Year.

I’m home sick today with a nasty sinus infection, so I thought I would make a quick post about Linode. Last week (maybe two weeks ago now) I decided to give Linode a test drive by signing up for a Linode VPS 512. The increase in traffic to this site and the discussion forums has been significant enough over the past 6 months that I’ve been trying to stay ahead of the curve rather than falling behind (I personally hate a slow site). I’ve been coming up against my 40GB/monthly transfer limits with RIMU hosting even after setting up a CDN so I went looking for alternatives and found Linode.
I ran some quick and dirty benchmarks using Unixbench (1 parallel test) and here’s what I found;
|No||Guest Operating System||Architecture||CPU||Description||Results|
|1||CentOS 5.7||x86||1 x Intel(R) Xeon(R) CPU E5540 @ 2.53GHz||VMware ESX 4.1 HP BL490c G6||1010|
|2||CentOS 5.7||x64||2 x Intel(R) Xeon(R) CPU 5160 @ 3.00GHz||HP DL360 G5||935|
|3||CentOS 5.7||x64||4 x Intel(R) Xeon(R) CPU E5540 @ 2.53GHz||HP BL460c G6||1005|
|4||CentOS 5.7||x86||2 x Intel(R) Xeon(TM) CPU @ 2.80GHz||IBM x345 Series||387|
|5||CentOS 5.7||x86||1 x Intel(R) Xeon(R) CPU E5506 @ 2.13GHz||RIMU Hosting – XEN 1vCPU||290|
|6||CentOS 6.0||x86||4 x Intel(R) Xeon(R) CPU L5520 @ 2.27GHz||Linode Hosting – XEN 4vCPU||495|
Note: I currently use the IBM x345 Series server as my test and development server so I don’t have to worry about destroying my live production server.
A number of the servers above are virtualized with either VMware or XEN and some are physical. I’ve provided some comparison data in servers 1-4, the two of interest are 5 and 6.
You can see from the numbers that the Linode server beat out the RIMU server by quite a margin. I also chose to have the Linode server placed in their Newark, NJ data center which is geographically closer to me in Pennsylvania than the Dallas, TX data center that my current VPS resides in. With that location change I noticed a big delta in the RTTs to/from the two locations. From my Verizon FiOS home broadband I get around 50ms to the Dallas, TX data center while I’m getting around 20ms to the Newark, NJ data center.
There are other pros and cons between RIMU and Linode which I won’t completely go into here but in my specific example it was the storage and transfer bandwidth that caused me to look elsewhere. I have nothing bad to say about RIMU, they’ve given me more than 18 months of great service.
Last week I moved the blog (that’s this site) to the Linode VPS and it seems to be running great. If everything continues to run smoothly I’ll migrate the discussion forums and remaining sites over to Linode and cancel my RIMU account over the next two weeks.
Have you noticed the speed increase or any other issues with this site?
It’s that time of year again… where I review the overall success and cost of running this blog (and forums) and I post some general thoughts about the past year and try to solicit new ideas for the future. I’m totally amazed when I think that it’s been 4 years now since I started blogging back in October 2007 on Blogger. Technology has come a long way in those 4 years as have I both professionally and personally.
While I haven’t been winning any awards for my journalist talent it has been rewarding to hear the feedback from all the wonderful people that I’ve met either on my blog or in the discussion forums. I’m hoping to round up some guest bloggers in the future and try broadening the topics I generally cover. If you’ve got a knack for technical writing and you’d like to see your name in lights please drop me a line.
The forums have been a pretty big success in my opinion although there’s still a lot more I’d like to see us achieve. I’ve had a lot of help which I need to acknowledge here from Flintstone, Dominik, Paul and Artur. Without these guys the forums wouldn’t be half the place they are today. Thanks guys!
The forums have grown tremendously over the past year, we’ve seen a 359% increase in overall traffic with some 51,116 unique visitors to the forums generating some 81,766 visits and 239,651 pageviews in total. We have a total of 681 registered users with 421 users have made at least one post or more. Over the past year we’ve had visitors from 125 different countries.
The financials are pretty straight forward. In calendar year 2010 I paid out around $378.42 to GoDaddy, and RIMU for domain names, hosting, etc. I collected around $367.41 in advertising revenue which came from Google Adsense and a few direct advertising sales. So while we were in the red again this year I was only down $11.01 which made my wife quite happy.
Let me say “Thank you” to the sponsors and all those that take the time and effort to follow my blog.
There’s been a slow but stead increase in blog traffic over the past 12 months. Looking at some of the Google Analytics data I can see that there has been approximately a 94% increase in visits (23,633), unique visitors (17,944) and pageviews (44,489) comparing the June-July 2011 timeframe to the same timeframe in 2010. Over the past year there were some 159,872 unique visitors to the blog generating some 232,498 visits and 440,725 pageviews in total.
The traffic increase has been steady enough that I’ve had to investigate CDN solutions and deploy caching plug-ins such as W3TC in an effort to keep up with all the traffic. In January we received a free upgrade from RIMU that we applied to the VPS and increased our memory from 480MB to 740MB. With the upgrade we were able to increase the number of web clients we can support concurrently. We were also able to install APC to help with PHP caching and increase the amount of caching within MySQL all in an effort to boost the servers overall performance and decrease the time which it takes to serve up the content to you the user.
I’m not sure what the future holds. The global economy has been all over the place this past year and the uncertainty ways on everyone as people try to “do more with less”. You’ll probably find me here again next year blogging away. Perhaps I’ll make good on my last years claim to start making some screencasts.

Last week Avaya announced that it would seek to raise $1 billion in an IPO.
As Ben Levisohn recently pointed out in the Wall Street Journal “The IPO game is notoriously dicey for retail investors”, but for the companies going public it can provide a windfall of cash to help drive R&D and additional product development. With the recent results of the LinkedIn offering I can see why Avaya might be enticed to jump into the market. However, the IPO game is getting crowded with Pandora going public today (surged to $26 share but dropped back to $18 a share later in the session) and Groupon, Facebook, Twitter and Zynga all looking to possibly go public sometime later this year.
Thursday’s filing disclosed Avaya has lost more than $3.6 billion since it was taken private in 2007 in an $8.3 billion buyout. The engineers of that deal, Silver Lake and TPG, own a 72 percent stake in Avaya, according to Thursday’s filing.
In the past year, Avaya has introduced more than 60 new products and services to boost its revenue. Through the six months ending March 31, Avaya’s revenue totaled $2.76 billion, a 16 percent increase from the same period last year. But its losses have widened to $615 million in the current year from $421 million the previous year.
I will say that I was surprised at the financials reported above in the Yahoo Finance news post. With Avaya selling stock publicly they’ll now need to file quarterly statements with the SEC something they haven’t had to-do as a privately held company. I’m curious if the red ink will drive away future or existing customers. What do you think?
