Very Slow Sending Speed

I have added already scraped 600K websites to the projetc. Project only makes check+send. It does not use capthca breaker. So it only sends messages to forms without capthca.

It uses 50 threads to send, and have 200Mbps download speed.

It can only send 25K pages during 24 hours. Lately I remember that I sent 100K in 1 day.

Isnt 25K/day slow, without scraping?

This is a big problem in this time. I hope it will solve soon. 

Really
