Checking Website Performance Effectively
Most website monitoring services send an e-mail after they detect a server outage. Maximizing uptime is important, but it's only area of the picture. It seems that the expectations of Online users are increasing all the time, and today's users won't wait extended for a page to load. When they don't be given a response quickly they will move on to your competitors, usually within just a few seconds.
A good website monitoring service is going to do much more than simply send advice when a status virginaustralia.com. The most effective services will breakdown the response duration of a web request into important categories that will permit the system administrator or web developer to optimize the server or application to offer the best possible overall response time.
Listed below are 5 key components of response time for an HTTP request:
1.DNS Lookup Time: The time it takes to get the authoritative name server for that domain and for that server to eliminate the hostname provided and return the right IP address. If the time is too long the DNS server should be optimized in order to provide a faster response.
2.Connect Time: This is the time required for the web server to reply to an incoming (TCP) socket connection and ask for and to respond by setting up the connection. If this describes slow it always indicates the operating system 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 both sides to negotiate the handshake process and hang up up the secure connection.
4.Time to First Byte (TTFB): The time has come it takes for the 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 and other inefficiencies associated with application development.
5.Time and energy to Last Byte (TTLB): It is now time needed to return every one of the content, after the request continues to be processed. If this describes taking too long it usually suggests that the Internet connection is just too slow or is overloaded. Increasing bandwidth or acquiring dedicated bandwidth should resolve this issue.
It is extremely hard to diagnose slow HTTP response times without this information. Without the important response data, administrators remain to guess about the location where the problem lies. A lot of time and money could be wasted attempting to improve different pieces of the web application with the aspiration that something will work. It's possible to completely overhaul an internet server and application only to discover the whole problem was actually slow DNS responses; a challenge 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 to diagnose and correct performance problems efficiently.
