Almost excellent plugin

I really like this plugin very much, and is very handy. I love that it supports almost all the networks i need.
BUT
I have a small issue in my case which causes me lots of problems.
In my blog i publish more than 1000 new posts every day, and although i do want to autoshare them in the social networks, i dont want to auto share all the posts. Because its spammy.
SNAP has a nice feature to limit the posts by setting delay between each post update, BUT it doenst work.
I’ve tried all settings and did many checks, but it doesnt work. It keep up posting all the posts and not only that, for each autopost it does, it creates a new PHP thread in the server and in my case it ends up killing my server by overwhelming PHP Threads.
So i please ask you to consider making it more light or less resources hungry and fix that autoposting limits.
thank you
