Tweaking my RR!

Post by Vic Mackey »

Is there any changes that could benefit my connection? Im on RR, I honestly dont know what my max download is supposed to be. When I ran a speedtest near me I got 6.5mb/s.

Ok I changed it and this is what it looks like now:

« SpeedGuide.net TCP Analyzer Results »

IP address: xx.xx.xxx.xx

TCP options string: 020405b40103030001010402
MSS: 1460
MTU: 1500
TCP Window: 64240 (multiple of MSS)
RWIN Scaling: 0
Unscaled RWIN : 64240
Reccomended RWINs: 64240, 128480, 256960, 513920
BDP limit (200ms): 2570kbps (321KBytes/s)

MTU Discovery: ON
TTL: 50
Timestamps: OFF
SACKs: ON
IP ToS: 00000000 (0)

I ran the speed test again and got 6698kbps down and 491kbps up. Does this look right?

Settings look correct. Test speed at this link using a few nearby test servers and post your results:

TCP Receive Window - 128480
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - checked
Timestamps - uncheck

Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect
