I'm using wshaper in the Oleg firmware and it seems to be slowing down my download speed by half!

Here's one of my speedtest result with wshaper off:

It is what I usually get during non-peak hours.

I start wshaper in my post-firewall but for testing I just used this command:
Code:
wshaper start vlan1 11000 450
But when I run the speedtest again, I only hit at most ~4000! It doesn't matter what values I set cos it never goes more than ~4000. Am I using wshaper wrongly? I just want to test this out before I do any further QoS.
