Varnish: Initial lag before dumping output to the browser

[Caunter, Stefan]

You likely need to check with yslow for elements that are synchronous and therefore blocking speedy browser rendering. Follow those rules especially the parallel downloads. Varnish cannot help bad page design.

Hi,

If you run a tcpdump on your client, do you see any packet exchanged
or the traffic is on hold for the 3-4s?
Do you have this behavior when browsing the backend directly?

cheers
