I still do not understand why this is still being targeted to Win 7 users. Just my 2 cents.

**Philip** · 09-17-11, 02:51 PM

The TCP Optimizer is targeted toward all Windows users, it includes a number of settings for tweaking Windows 7 as well.

When will there ever be a new guide for this program? The interface isn't even close to version 2.0, albeit the mouse over text is most helpful. Took me forever to notice it LOL

**Philip** · 09-17-11, 06:27 PM

The program detects the OS and the interface differs depending on the available settings for your particular OS... We do have a tweaking article for Windows 7/Vista/2008 that explains most of the settings in detail, however, you're right that we need to update the documentation.

Hi all, thx for this update of this great tool!!
With the last builds i used Optimal setting, but now i see a gamer option, im not a gamer, i never play, so: is optimal setting always the good setting or must i modifiy a thing in Custom??
thx!

**Philip** · 09-19-11, 09:21 AM

The "Optimal" settings are still best for most people.

There are a couple of Gaming tweaks in the Advanced tab, and the "Optimal" settings already change one of them that we believe will benefit most users.
The other gaming tweak (disabling nagling) is specific to some games, and we do not recommend changing it for normal internet use as it has some downsides. You can check the Windows 7 tweaking article for more information on each of those settings if you'd like.

Thanks for the nice words about the program, we try.

**dafmat71** · 09-19-11, 09:24 AM

OK, so i let it like that!! THX a lot!!

**100 010 00** · 09-25-11, 03:11 AM

bravo philip.... continue with this job

Another thing. Just below "networkthrottlingindex" value, is the "SystemResponsiveness" value which indicates the amount of cpu load that is being used for multimedia against network. Let's say that a value of 50 helps alot for game playing. test it and if u like it u can add it in nagle algorith session with no recommendation. Servers have a value of 100 i think.

Another one. I think there is a little bug with ie connections. When u apply the settings the pop up "apply window" shows no change in those 2 values and the values are opposite between them. U change maxconnectionsperserver and shows the change for 1_0 servers setting. but the values are written with the right way in registry. is a monitor bug only. take a look at this.
The tip here (i mean in the same path), is that u can tweak MSN and SKYPE with the value of 8, default is 6. They work better under value 8 when u use a video conference. Take a look at this also.

Hello,

it's a really goog program, but i miss some features.

i have a 3G/UMTS Modem (HUAWEI Mobile Connect - 3G PC UI Interface) from the
German telecom to connect my computer via GSM/UMTS with the internet.
But the "Huawai" Adapter is not listed in the "network adapter selection" of
TCP Optimizer - is there no support for those GSM/UMTS modems ???

Can you convert the online help/documentation and the FAQ of TCP-Optimizer
to a PDF document and link to it (after downloading together with TCP-Optimizer)
in the "help" menu of TCP-Optimizer - thus we can read the documentation
offline ??

Is it possible to get a language file of TCP-Optimizer to translate it to other
languages like german ?

Greetings from Germany

Ralf

Great Tool! Thanks

EDIT:
Is there a discussion in the forums about this or just through the article located here: http://www.speedguide.net/articles/w.../p-4/#comments ???

**timerrington** · 07-07-12, 01:13 AM

Will there be an update of this program that will work with Windows 8?

**jonathansmith** · 08-22-12, 03:06 AM

It is good to use TCP optimizer for security purpose i have used it. Hope this will also add positive value regarding security purpose.

**Michael Avanessian** · 09-24-12, 08:20 PM

Doesnt work for me on a new clean install of Win7 64bit all patched up. All drivers are WHQL tested.

I also do not understand why this is still being targeted to Win 7 users. Just my 2 cents.

Why? I still have Win7 64 bit. It's probably the last upgrade I'll ever do, I'm getting tired of PC's and upgrades. I'm not tired of modding though.

your message is now very old, it should be talking about win 8 ... :/

How about ACTUALLY reading the OP??? it is targeted (YOUR word, not SG!! ) "all Windows OSes from Windows 9x to the latest Windows 7" and that will change soon to 8....

**DMichael** · 02-01-13, 06:34 AM

bug:
tcpdelackticks its not detected..its says default when the value on 0

**100 010 00** · 02-25-13, 09:39 AM

Hi philip.... its an old patch but as i can see, u have not include it in the tcp optimizer but it works fine. it goes with nonbesteffortlimit and is about for the limit of outstanding packets.

"MaxOutstandingSends"=dword:00000000

**Philip** · 02-25-13, 10:34 AM

AFAIK, the MaxOutstandingSends is a QoS Packet Scheduler-specific setting. If it is not configured in the registry (or disabled), it does not limit the number of outstanding packets. If you specify a number, it then limits the number of outstanding packets, the scheduler postpones all submissions to network adapters until the number gets below this limit. In other words, if the setting is not in the registry (default), it is not limiting the number of outstanding packets.
