Time to first byte

Hi everybody

when i’m checking my site using webpagetest, then it is taking more time for time to first byte.
What can be the reason behind that?

Thanks,
Rahul.

That is usually caused by your application logic (database performance and calls more often than not) and it’s not something we have visibility into from the outside. The best bet is to install an APM solution like New Relic or to instrument your server code to figure out where the time is going.
