Time to First Byte
The short form is TTFB this metric records the first time data reaches the visitor on Browser searching. In simple terms, this is the time taken for information to reach the client from the server. If the time is long bounce is evident. Thus, TTFB is dependent upon the time taken by the server to reach the client or front end, and the time the front end takes to present it to the visitor. Thus TTFB measures the network latency and server processing. This is a good way to access the client-server performance. The time should be lower than 200 milliseconds.
Round Trip Time
Round Trip Time (RTT) works on the same basis sending and receiving from the client to the server. Network latency causes round-trip delay and increases RTT. Since data can travel over different network paths the results can vary as per network monitoring tools. As the name suggests network monitoring tools monitor vast aspects of the network and present results and graphs.
Ping Command
Although useful in determining the return of 32 KB of data, it is inaccurate when tried on a multi-pathway.
Disk Latency
This is the time taken to store and read data. Latency simply means being late and is applicable all over the Internet. Writing a large number of files leads to delay therefore solid state drive is faster than a hard drive.
Fiber-optic Latency
The sunlight takes time to travel, a particular distance through a fiber optic cable. At the speed of light, a latency of 3.33 microseconds occurs for every kilometre. In the case of fibre-optic cable, each kilometre causes a latency of 4.9 microseconds. If there is a structural fault considerable high latency can occur leading to slowing the transmission.
Operational Latency
This time lag happens due to faulty computing operations. Considerable latency is caused. This happens when one continues opening pages and clicking diverse elements. There is a shortage of traffic jams, thus, latency becomes a key factor as far as the system performance is concerned.
As mentioned above late data transmission is dependent upon many factors and rectification is an urgent requirement. This should be within the grasp of all SEO Specialists especially those dealing with system administration.
