PC & MAC CLINIC - On line problem solving. (CPU)     

Crocodile - 16 Dec 2002 03:59

Iain - 17 Mar 2005 20:32 - 3104 of 11003

Down stream 1647 Kbps (205.9 KB/sec) 1778 Kbps (inc. overheads)
Upstream 238 Kbps (29.8 KB/sec) 257 Kbps (inc. overheads)

What should it be?

The above is after DR TCP!

Kayak - 17 Mar 2005 21:05 - 3105 of 11003

Iain, this is mine with PlusNet.

Downstream 1841 Kbps (230.1 KB/sec) 1988 Kbps (inc. overheads)
Upstream 242 Kbps (30.3 KB/sec) 261 Kbps (inc. overheads)

It will be a bit variable during the day though depending on the ISP. As the speed gets higher you are more susceptible to second-by-second changes in network congestion. To get the maximum possible speed reading, test in the middle of the night!

In Dr TCP, MTU should normally be set to 1500, RWIN to 38400 is plenty.

If you are confident in editing the registry I highly recommend these two registry tweaks (assuming you have Windows 2000 or XP):

Maximum simultaneous connections in IE (drastically increases speed of loading of webpages)

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

Set MaxConnectionsPer1_0Server and MaxConnectionsPerServer to 16 decimal.

RWIN (does what Dr TCP does):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Set TcpWindowSize to 38400

1. In Tools, Internet Options, Security, Custom Level, Active X - controls and plug-ins, what settings should I best have?

2. What should I look for and set up to do with Java on my computer?

Kayak - 18 Mar 2005 09:00 - 3108 of 11003

Iain, set up as DWORD and enter as decimal.

Kayak - 18 Mar 2005 09:03 - 3109 of 11003

Doc, I have "Run ActiveX controls and plug-ins" and "Script ActiveX controls marked safe for scripting" set to Enable and the others to Prompt. With all these things, start with Prompt until you find there are too many prompts!

Not sure what you mean with the second question.

Iain - 18 Mar 2005 09:05 - 3110 of 11003

I dont know which DWORD Cant see MaxConnectionsPer1_0Server and MaxConnectionsPerServer

Kayak - 18 Mar 2005 09:07 - 3111 of 11003

Ah, you have to set them up if they're not there.

Kayak - 18 Mar 2005 09:13 - 3112 of 11003

Should go in the section with EnableAutodial and User Agent amongst others.

DocProc - 18 Mar 2005 09:16 - 3113 of 11003

Kayak

Thank you.

Re the Java, "Not sure what you mean with the second question."

Neither am I. :-)

Iain - 18 Mar 2005 09:57 - 3114 of 11003

Is that better?


Downstream 1874 Kbps (234.3 KB/sec) 2023 Kbps (inc. overheads)
Upstream 239 Kbps (29.9 KB/sec) 258 Kbps (inc. overheads

Kayak - 18 Mar 2005 09:59 - 3115 of 11003

Better than mine :-) The theoretical maximum for the 2023 figure is around 2048.

Iain - 18 Mar 2005 10:00 - 3116 of 11003

Result!!!! :-)

Kayak - 18 Mar 2005 10:02 - 3117 of 11003

The business with the Max-connections is to allow IE to load multiple pictures at once. The default is 4 I think, meaning that if IE loads a web page with 20 pictures then it will load 4 at a time. With 16 things run faster since it can load 16 at once. You should see it on the task bar in the bottom right hand corner where the URLs will change quickly.

For those using google and have Gmail acounts

"While the media has largely focused on the fact that Gmail will scan the contents of your email messages in order to target ads, the more serious problem from a privacy perspective is Google's ability to link your Gmail account information with your Google web searches. By linking your complete Google search history - tagged with your name and personal details - to your email records, Google can create a highly nuanced picture of you as a reader and as a person. Such pictures present irresistible targets for government investigators, civil lawsuit plaintiffs, and even identity thieves. A single attack or disclosure could release deeply sensitive details about your life to the world without your knowledge or consent.

Last year, there was also articles about one or more of the big email providers retaining, for some time, all deleted emails.

axdpc - 18 Mar 2005 20:13 - 3121 of 11003

post #3119 mentioned email retention, by US email providers.

Here is the EU bits ...

"January 11, 2005
The Price of Surveillance, Measured in Pounds
The London Internet Exchange (LINX), a consortium of ISPs, argues that the cost of a proposed EU plan to mandate data retention would amount to a tax to support government snooping.

EU Considers Data Retention Laws
The proposal could mandate permanent retention of user information related to phone, text, MMS, email, Voice over IP, and Web communications.
