Best settings for gaming QoS+DSCP

[SirSWE]

What did you change to?

[-taz-]

openwrt-sfe-flowoffload
but in my case it is better gargoyle

[SirSWE]

My friend said it was much smoother with Software flow and hardware flow enabled. Did you use fq_codel with cake?

[-taz-]

fq_codel

[SirSWE]

I dont know what games you are playing but it was alright in the older CoD titles , I still prefer Gargoyles qos. Me and my friend had some bad experience with Sfe + flow offload in modern warfare.

[-taz-]

if that's why I went back to the gargoyle it's better in games

[SirSWE]

Yeah I noticed 1.12 is much smoother then 1.11.

[VanCleef]

Are you both using DSCP or just qos gargoyle?

if you analyze with SG TCP / IP Analyzer from https://www.speedguide.net/ With the IP assigned to EF, you will know that DSCP is working with EF and if you analyze with Mobile or another separate PC, it will result in DSCP CS1

I use this site to know the mtu, but did not realize that also showed the field tos/dscp! nice find
