Most website monitoring services send an e-mail when they detect a server outage. Maximizing uptime is important, but it's only section of the picture. It seems that the expectations of Online users are increasing all the time, and today's users will not wait extended for a page to load. Should they don't be given a response quickly they will move on to the competition, usually within just a few seconds.



A good website monitoring service can do much more than simply send advice when a robertsspaceindustries.com. The very best services will breakdown the response time of a web request into important categories that will allow the system administrator or web developer to optimize the server or application to provide the best possible overall response time.

Listed here are 5 important components of response here we are at an HTTP request:

1.DNS Lookup Time: Enough time it takes to get the authoritative name server for that domain and then for that server to resolve the hostname provided and return the correct IP address. If the time is too long the DNS server has to be optimized so that you can provide a faster response.

2.Connect Time: The time has come required for the internet server to reply to an incoming (TCP) socket connection and request and to respond by creating the connection. If this is slow it always indicates the os is trying to reply to more requests than it can handle.

3.SSL Handshake: For pages secured by SSL, the time has come required for each side to negotiate the handshake process and set up the secure connection.


4.Time for you to First Byte (TTFB): This is the time it takes for the web server to respond with the first byte of content following your request is distributed. Slow times here typically mean the net application is inefficient. Possible reasons include inadequate server resources, slow database queries along with other inefficiencies linked to application development.

5.Time for you to Last Byte (TTLB): The time has come needed to return all of the content, following the request continues to be processed. If this is 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 challenge.

It is extremely difficult to diagnose slow HTTP response times without all of this information. With no important response data, administrators are left to guess about in which the problem lies. Considerable time and money may 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 an internet server and application only to discover the whole problem was actually slow DNS responses; an issue which exists on a different server altogether.

Use a website monitoring service that will a lot more than provide simple outage alerts. The most effective services will break the response time into meaningful parts that can allow the administrator in order to identify and correct performance problems efficiently.
