Most website monitoring services send an e-mail when they detect a web server outage. Maximizing uptime is essential, but it's only area of the picture. It would appear that the expectations of Internet surfers are increasing constantly, and today's users will not wait extended for a page to load. When they don't get a response quickly they'll move on to the competition, usually in a matter of a few seconds.



A good web site monitoring service will do much more than simply send a reminder when a status abs-cbnnews.com. The very best services will breakdown the response period of a web request into important categories that will permit the system administrator or webmaster to optimize the server or application to offer the best possible overall response time.

Listed here are 5 key components of response time for an HTTP request:

1.DNS Lookup Time: Time it takes to obtain the authoritative name server for that domain and for that server to eliminate the hostname provided and return the appropriate IP address. If this time is too long the DNS server has to be optimized in order to provide a faster response.

2.Connect Time: The time has come required for the internet server to answer an incoming (TCP) socket connection and ask for and to respond by creating the connection. If this describes slow it usually indicates the operating system is trying to respond to more requests laptop or computer can handle.

3.SSL Handshake: For pages secured by SSL, it is now time required for each side to negotiate the handshake process and hang up up the secure connection.


4.Time to First Byte (TTFB): This is the time it takes for that web server to react with the first byte of content after the request is shipped. Slow times here almost always mean the internet application is inefficient. Possible reasons include inadequate server resources, slow database queries along with other inefficiencies linked to application development.

5.Time to Last Byte (TTLB): It is now time needed to return all of the content, following your request continues to be processed. If this describes taking too much time it usually shows that the Internet connection is too slow or perhaps is overloaded. Increasing bandwidth or acquiring dedicated bandwidth should resolve this issue.

It is extremely challenging to diagnose slow HTTP response times without all of this information. With no important response data, administrators are left to guess about where the problem lies. Lots of time and money can be wasted attempting to improve different pieces of the web application with the hope that something will continue to work. It's possible to completely overhaul a web server and application only to discover the whole problem was actually slow DNS responses; a challenge which exists on a different server altogether.

Make use of a website monitoring service that will a lot more than provide simple outage alerts. The best services will break the response time into meaningful parts which will allow the administrator to identify and correct performance problems efficiently.
