A good web site monitoring service will do much more than simply send advice when a webmail.juno. The most effective services will break up the response duration of a web request into important categories that will allow the system administrator or webmaster to optimize the server or application to provide the best possible overall response time.
Listed below are 5 important components of response here we are at an HTTP request:
1.DNS Lookup Time: Time it takes to find the authoritative name server for the domain as well as for that server to resolve the hostname provided and return the correct IP address. If this time is too long the DNS server must be optimized to be able to provide a faster response.
2.Connect Time: This is the time required for the internet server to answer an incoming (TCP) socket connection and ask for and to respond by setting up the connection. If this is slow it always indicates the operating-system is trying to respond to more requests laptop or computer can handle.
3.SSL Handshake: For pages secured by SSL, this is the time required for either side to negotiate the handshake process and hang up the secure connection.
4.Time for you to First Byte (TTFB): It is now time it takes for your web server to reply with the first byte of content following your request is shipped. Slow times here almost always 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 to Last Byte (TTLB): The time has come needed to return every one of the content, after the request may be processed. If this is taking a long time it usually indicates 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 this information. Minus the important response data, administrators are left to guess about in which the problem lies. Lots of time and money can be wasted attempting to improve different components of the web application in the hope that something will continue to work. It's possible to completely overhaul an internet server and application only to find out the whole problem really was slow DNS responses; an issue which exists over a different server altogether.
Use a website monitoring service that does a lot more than provide simple outage alerts. The very best services will break the response time into meaningful parts that will allow the administrator to diagnose and correct performance problems efficiently.
