Hi guys,
I'm trying to figure out is there any relationship between
Currently, I'm shaping ~1 Gbit/s of traffic (around 1500 users) using pipes and tablearg, giving 10 to 100 Mbits per each user.
A lot of users complaining about the low speed, I've checked everything in between and now I want to make sure that dummynet is not an issue here.
Here's an example of my dummynet pipes:
Here are all the parameters for dummynet in sysctl:

kern.hz parameter and dummynet performance in terms of traffic shaping. Not it's by default = 1000. But is there a need to change it when you have more pps or interrupts?Currently, I'm shaping ~1 Gbit/s of traffic (around 1500 users) using pipes and tablearg, giving 10 to 100 Mbits per each user.

Here's an example of my dummynet pipes:
Code:
ipfw pipe 10 config bw 10760Kbit/s queue 60 mask dst-ip 0xffffffff gred 0.002/10/30/0.1
