Is there any way to show the load time of each component at page level in request.log file so that I can use this time in my application ?

In AEM 6.2 we can get the loading time of each component in touch Optimized UI in Developer Mode But It depends on server. Other way is that we can use timing component  but it also server dependent because we have to include this component in global.jsp.

But I want the loading time of each component on client side. If anyone can help me Please give me some suggestions.

Here is the only applicable article:

However - this is server. Does not look like there is a tool specifically for client side.

You can look at using general tools that measure the time it takes to load a page - for example - Chrome tool:

There are other tools as well that show client loading time.
