Whenever your browsing the web I’m sure you’ve run into many websites that have horrible loading times. If your sites are slow this can impact your customers and your business.
Here’s some helpful hints to get you headed in the right direction:
1) Host any dynamic website on apache whenever possible - it will run fast and handle heavy loads with ease
2) Use tools like YSlow from Yahoo! to get suggested speed fixes on all your sites.
3) Build caching into your custom web sites and utilize caching in any existing frameworks when provided.
4) Take the time and energy to go through both your apache httpd.conf and your php.ini (if applicable) and verify you only have necessary features enabled. Adding extra bloat to your server will slow it down - and make handling heavy amounts of traffic more difficult.
5) Monitor your log files for software bugs and when you’re content with a running site - disable all non-critical logging as the server error logging can cause some delays.
6) Use the built in apache benchmarking tool called ab - you can’t go wrong with this tool.
7) Get in touch with a Professional for some additional tweaks, testing and benchmarking. Typically a small investment can leverage large gains in performance.
Starting with the suggestions above you should be well on your way to reducing your page response times by at least 50%.

from Lifehacker: “It’s known that most spam (particularly malware such as keyloggers) originates overseas (Estonia, Moldavia, China, Poland, etc.) By blocking email from most of the undeveloped world, I’ve successfully reduced spam by 95 percent in the past year. In Outlook, click Actions > Junk E-Mail > Junk E-Mail Options. Click the International tab, then the Blocked Top-Level Domain List button. Now select the countries you wish to block.”
Very handy little tip.

“Following old-school backup routines for data backup could put your business at risk. To avoid disaster, you need to think about what data you need to recover—and how quickly.
When it comes down to the nitty-gritty details of backup, most small-business owners (along with most individual users) have a less-than-solid grasp on the reality of their backup needs. This knowledge gap should come as no surprise, since the path of least resistance is to follow the tradition of daily backup, rather than taking the time to examine one’s workflow and determine real needs.”

“Wireless networks, like their wired counterparts, rely on the manipulation of electrical charge to enable communication between devices. Changes or oscillations in signal strength from 0 to some maximum value (amplitude) and the rate of those oscillations (frequency) are used singularly or in combination with each other to encode and decode information.”

“Over the last ten years, our world has become interconnected in ways not previously imaginable. Today, for instance, people in Spain, the US, and Brazil can find out simultaneously that soccer-star David Beckham has switched teams. Small companies can now affordably be spread across the globe, and big companies can now have inter-office collaboration on a daily basis. But all of that interconnectedness relies in large part on our ability to protect the networks that create those connections.”
