No actual problem, more of a "curiosity" thing.

Hi guys, I've been using TCP optimizer ever since I find out about it (long time ago...) and mostly, I just check "modify all network adapters", "optimal" and apply and that's that. The thing is, lurking around these forums I've seen A LOT of posts asking for help with custom settings and APPARENTLY, most of the time they seem to work more effectively than by just using "optimal".
So I thought I'd try it and see if it makes any difference.
Even though I'm not asking for help with any specific issue I'll try to post as much info as I can.

- Advertised speed: 10/1Mbps
- Actual speed:

(As you can see, I'm doing pretty decent actually so it's more of a "if I can improve upon it, why the heck wouldn't I?)
- ISP and type of connection: Telefonica del Peru/HFC
- Current settings:

Code: Select all

- As a side note, I generally use Chrome for every day browsing. But I'm aware that Chrome plays by its own rules most of the time so I figured it would be best to run the analyzer with I.E 10 (as you can see by the results I've posted).

If you need anything else, please let me know. I'm really looking forward to diving into custom settings to see if I can squeeze every last ounce of "internet juice"

Thanks in advance guys.
All the best.

*EDIT* Seems I'm not doing so good after all. Out of curiosity I took a pingtest to see how well I was doing with that and to my surprise I have a 2% packet loss.

Any idea what could be causing that?

Wow, 161 views and not 1 reply? Are these boards even alive?
Not complaining, merely asking...

There seems to be quite a difference between your speed and ping tests... Seems your speed test is with your ISP, and the pingtest is not, i.e. you get great speed/ping to your ISP and terrible latency after that.

You can get a clearer picture with a traceroute to a server far from you, for example try the following in command prompt: tracert speedguide.net
It shows the latency to each hop along the route to our server.

The only thing that stands out with your settings you may want to try playing with would be this --> IP ToS: 00100000 (32)
If your ISP honors your changes, you can bump up the priority of your traffic. There is more info on that here: http://www.speedguide.net/tcpoptimizer.php#advanced_qos

And I read the link you posted about IP ToS. I was wondering how would that benefit me and how would I do it? There's an explanation for what the setting does. But not about how to modify it. Could you elaborate a bit more please?
Thanks again.
