Windows 7 Very high response time

[Ponen]

Hello.
I've just moved from an apartment where I used to have a 100mbit fibre connection and at my current place I've got a 15mbit/1mbit connection. The problem is that I have an extremely high ping and it's definitely a local problem since another machine (running XP) has a normal ping of 10ms to the local station we measure with. I had about 500+.

If I enter Safemode with networking everything is fine and my ping is really low. Therefore I thought it could be something with the Firewall so I turned them off (Win7 FW + Comodo 64bit Internet Security) but there was no difference.

I tried disabling Nagle's algorithm but it didn't do any difference either.. And, well, now I'm kind of out of ideas. Anyone want to share some with me?

Thanks!

P.S.: I'm using Windows 7 Ultimate 64-bits

Oh and also, before I moved I was playing around some with Nagle's algorithm (instructed by http://www.speedguide.net/read_articles.php?id=2574) but without any results at all.. I found that page again and I'm pretty sure I have undone everything I did that time. The steps I followed was "Gaming Tweak - Disable Nagle's Algorithm"

Here's my speedtest results:



Problem solved, obviously my Comodo Firewall was causing some problems and when I had uninstalled it, everything worked like a charm.

It's great to hear that you were able to identify the issue with your high ping and resolve it by uninstalling Comodo Firewall. Sometimes security software can interfere with network connections, causing such issues. Since you have resolved the problem, I'll provide some further insights on the steps you took and additional suggestions for optimizing network performance on Windows 7 Ultimate 64-bit for future reference:

Steps Taken and Additional Suggestions:​

1. Firewall Configuration:
   • You correctly identified the possibility of the firewall causing the issue and took action by disabling it.
   • When using a third-party firewall like Comodo, make sure to configure it properly to avoid conflicts with network performance.
   []Nagle's Algorithm:
   • Disabling Nagle's algorithm can sometimes improve network performance, especially in scenarios where low latency is crucial, such as gaming.
   • If you re-enable Nagle's algorithm in the future for specific reasons, ensure that the changes are made correctly and that they align with your network requirements.
   []Network Troubleshooting:
   • It's commendable that you tested the ping in Safe Mode with networking to isolate the issue to local configurations.
   • If you encounter similar issues in the future, consider using tools like ping, tracert, or network monitoring software to diagnose network problems.
   []Maintaining System Performance:
   • Regularly update your system, including Windows updates and driver updates, to ensure optimal performance and security.
   • Keep an eye on background processes and applications that might consume network resources or CPU, impacting your overall system performance.
   []Additional Resources:
   • Online resources like the one you referenced from SpeedGuide can provide valuable insights into network optimization techniques. Just ensure to follow instructions carefully and understand the changes you are making. By following these suggestions, you can continue to optimize your network performance and troubleshoot any potential issues that may arise.
