How can I reduce the waiting ttfb time

Question

I have a query which involves getting a list of user from a table in sorted order based on at what time it was created  I got the following timing diagram from the chrome developer tools     You can see that TTFB  time to first byte  is too high   I am not sure whether it is because of the SQL sort  If that is the reason then how can I reduce this time   Or is it because of the TTFB  I saw blogs which says that TTFB should be less   lt  1sec   But for me it shows  1 sec  Is it because of my query or something else   I am not sure how can I reduce this time    I am using angular  Should I use angular to sort the table instead of SQL sort   many posts say that shouldn t be the issue   What I want to know is how can I reduce TTFB  Guys  I am actually new to this  It is the task given to me by my team members  I am not sure how can I reduce TTFB time  I saw many posts  but not able to understand properly  What is TTFB  Is it the time taken by the server

If you are using PHP  try using  lt  php flush      gt  after  lt  head gt  and before  lt  body gt  or whatever section you want to output quickly  like the header or content   It will output the actually code without waiting for php to end  Don t use this function all the time  or the speed increase won t be noticable   More info

TTFB is something that happens behind the scenes  Your browser knows nothing about what happens behind the scenes   You need to look into what queries are being run and how the website connects to the server   This article might help understand TTFB  but otherwise you need to dig deeper into your application

I would suggest you read this article and focus more on how to optimize the overall response to the user request  either a page  a search result etc    A good argument for this is the example they give about using gzip to compress the page  Even though ttfb is faster when you do not compress  the overall experience of the user is worst because it takes longer to download content that is not zipped

The TTFB is not the time to first byte of the body of the response  i e   the useful data  such as  json  xml  etc    but rather the time to first byte of the response received from the server  This byte is the start of the response headers   For example  if the server sends the headers before doing the hard work  like heavy SQL   you will get a very low TTFB  but it isn t  true    In your case  TTFB represents the time you spend processing data on the server   To reduce the TTFB  you need to do the server-side work faster

I have met the same problem  My project is running on the local server  I checked my php code     db   mysqli connect  localhost    root    root    smart      I use localhost to connect to my local database  That maybe the cause of the problem which you re describing  You can modify your HOSTS file  Add the line     127 0 0 1       localhost
