Improve TTFB

Just care that the cache is always warmed and use the cache crawler for cache warmup. That will improve TTFB dramatically.

Thank You. How i can use the cache crawler for cache warmup ?

Documentation is your friend:

Thank you ??

Nothing changes about the TTFB unfortunately. Do you have another ideas?

You’re using quic.cloud, which is good for connection times, but if quic.cloud doesn’t have your pages in the cache, your server will be requested to load the data. Unfortunately, your server is very weak and your site is not optimized either. Above all, you have much too large pictures. You should therefore optimize your site better first. Above all, use the webp replacement function so that less data has to be loaded.

FYI: A CDN or quic.cloud can only show its advantages if your site is optimized as best as possible. Also, your site seems to have little traffic, which means that it takes a long time for quic.cloud to cache your pages.

I already optimize my website and serve images in Webp.

Everything is possible is optimized. So i don’t understand why my TTFB is not good. Maybe another plugins or my hoster

As already said, if URLs are not cached at quic.cloud request goes to your server and this takes time. That means push the traffic at your site to get the URLs cached by quic.cloud.

Ok. But i put Crawler on. So it helps to cache the url not ? Or i don’t understand.

Yes it does, but the crawler can only warmup the cache at the origin (your own) server and not the cache at every QC node.

Ok. So the only solution is to have more traffic ?

Not exclusively, but if the cache on your own server is already warmed up, then it doesn’t take that long for QC to load the data from your server if a QC node doesn’t already have the requested URL in the cache. If QC does not yet have a requested URL in the cache, you still have an advantage because a QC node may be closer to the location of the user who requested your page.

However, and you should know this, a CDN only makes sense if the majority of your site visitors are not from your own country. If this is not the case, visitors from France may have to wait longer than without a CDN, because your server is usually faster than a CDN node from your own country.
