Speed optimisation / LSCache

Hi there,

I am using Openlitespeed 1.5.4 / LSCache / Cloudflare CDN / Wordpress on over powered ubuntu server.
Over all I am getting excellent performance.
I am wondering tho, why after the last asset is loaded from my web server why there is such a big gap when loading the deferred items like google tag manager etc?
Is there anyway to make that start to load as soon as that last file has loaded?

Thanks Rudi
