D-Link DWA-552 Extreme N Desktop PCI Adapter has three antennas. It has better range and higher speed than DWA-525. It is easy to mixup these two module numbers. DWA-525 has one antennas. N150 DWA-552 has three antennas. N300, double speed of above in the idea environment.
The oldest one is WUA1340, I got five years ago. DWA-525 just weeks ago. The LinksysAE2500 I got this week.
WUA1340 is G only. DWA-525 and AE2500 support 802.11n network. Based on the theory, DWA-525 is 3 times faster than WUA1340, AE2500 is 2 times faster than DWA525. But, the reality may be different. Let me show you the fact based on my personal test of the speed to copy a large file.
Shaw Cable technician came this morning, and just connected my Cable in the meter room. He said it is not necessary to come into my house.
I looked at the cable modem lights, it works. I confirmed it and said thank you to him.
It is 25Mbps download Maximum, and 2.5Mbps upload Maximum on my one year contract with CIK. $30 per month.
Now I tested the speed with Speedtest.net service. The result posted above.
It is better than my expectation.
From this month, I switch from Shaw to Telus. I am just using Internet and Basic TV. When I am with Shaw, I have to pay $89.49 a month including tax. Which is including Personal TV package and High-Speed Internet.
Now I am using Telus. Including Optik High Speed and Optik TV Essentials. The deal is $19.95 per month plus tax. Total is about $22.35.
It is one year contract.
Let me see the speed first. I am heavily user of Internet. There are 3 Desktops, 2 Laptops, and a lot of wifi devices.
Essential TV package has about 30 English TV channels. Which also include Free HD channels.
To double the traffic, one of the optimization steps is to test the load time of page and find the way to speed up.
I recommend WebPagetest. It is a free tool to test your blog / web page. See how fast to load the whole page. It tests two time, one is fresh load, the other is repeat view.
I tested my home page of this blog. The result is pretty good. Page Speed Score: 97/100
Let us see how it is:
I moved one phpBB forum to a VPS. All fresh.
I have Apache installed and MySQL. phpBB 3 relay on them.
Because of the size of forum, about 500K posts, 1000 users, the forum is not as fast as I think.
I have to do something to improve the performance of it. I still remember that some opcode optimizer can help.
There is a picture present the global download speed comparison, which is sourcing from Akamai.
First of all, I would like you to test your own Internet speed first. It is including Download speed, Upload speed, and Ping time.
I recommend the speed testing service of Speedtest.net.
Just a few minutes ago, I tested my Internet download speed in office. It is connected by Telus.
The result is following:
Testing between, Telus Internet user and Lynnwood, WA server.
Now I have my own current speed testing result. Let us see how about the rest of the world.
If you come my Blog often, you may fell the site is loaded faster than before. Yes. You are right. I implement CDN to improve my blog performance.
A content delivery network or content distribution network (CDN) is a system of computers containing copies of data, placed at various points in a network so as to maximize bandwidth for access to the data from clients throughout the network. A client accesses a copy of the data near to the client, as opposed to all clients accessing the same central server, so as to avoid bottleneck near that server.
Put CSS, js files and images to CDN is a good choice to save bandwidth of blog hosting. The key is cost of CDN is cheaper than web hosting.
It did keep site visitors happy. Get better browser experience from any spot of the World.
I purchased MaxCDN. $10 for 1000GB. I can not find any other CDN provider can beat this price.
I have a Shaw Cable High Speed Internet at home.
It has following features.
# Up to 5 Mbps download speed
# Up to 512 Kbps upload speed
# 60 GB/month data transfer
# 10 Personal email accounts
# 7 No Cost Extras
# Up to two IP addresses**
# 24/7/365 technical assistance
I tested the speed with my D-Link WUA-1340 Wireless G USB 2.0 Adapter.
Download Speed 4.7Mbps,
Upload Speed 449kbps,
Sounds OK with Shaw’s commitment.
The test tools is provided by Shaw Cable.
To have a more fair speed test results, I tried the third party online tool.
