View Full Version : Internet speed up

13-07-2003, 11:02 PM
Hi have had the internet for sometime now and was wondering,
If you have a modem that connects at over 40kbps,
why can you only download 1 item (proggie, or window) at 5-7kbps, and as soon as you start another download (proggie or window) it slows both downloads to around 2-3kbps?

Also can someone give me some suggestions on speeding these up, with

1, Software (ie, netants)
2, Regedit
3, Or someother means

Thankyou =)

Its all in the size of the letter b

Connect at 40 kbits/second.
Download at 5 kBytes per second.
There are 8 bits in a Byte (b=bit, B=Byte)
40,000 bits per second = 5,000 Bytes per second Maximum. Compression of data will speed it up, control and error correction will slow it down, so rule of thumb is factor of 8.

There is only the abiliy (at 40 kb) to get 5 kB down the line so if you share it between 2 files its half each.

Programs and files are in kiloBytes. Data bandwidth is kilobits.

2 things I use for speeding up my Internet connection.

1) DNS lookup Caching.

Every image, link etc. requires a DNS lookup. Each lookup takes 20-200ms depending on DNS server and link speeds. If you want to see how many links there are on a page, simply view the source of the web page you are on. (e.g. the Press F1 posting page has over 20 links.) And that is only one page. If you view many pages that is many lookups all adding to the delay oy loading those pages.

You can find lots of references to DNS caching on Google.

I use Naviscope (http://www.naviscope.com)
You can also use Fastcache from AnalogX(http://www.analogx.com/contents/download/network/fc.htm)

2) I use a RAM Drive on Windows 2000 or XP.

If you have more than 256MB this will be no problem. I change my Temporary Internet Folders to this virtual disk. I use one of 32Mb.

See http://members.fortunecity.com/qualitysoftware/RAMDisk/RAMDisk.htm

for details.

Note if you download a lot via Internet Explorer, you may want a drive as bigger than what you download.

Hope this speeds up you internet connection

> 1) DNS lookup Caching.

Its not as bad as you say. You browser doesn't do a look up for every link because most links will be to items on the same host. And more significantly your browser and most other apps will be doing DNS caching anyway.

Using more aggressive settings for your browser cache (eg "Once per session") can make pages load faster because it doesn't check for changes. At the cost of having to hit reload sometimes.
This is why Opera appears very fast, it defaults to only checking for changes every 10 hours.

Also...... if you are currently getting 5-7Kilobytes per sec download speeds then you are doing very well indeed for dial-up. That is as fast you can expect.

Maybe there are other people out there would dearly love that speed, tweak'e for one :)

terry please don't tease ;-)

<tweak'e drools at he mere thought of a 5k modem conection>

I thought you'd drool a little at those speeds tweak'e :)

Gosh it doesn't seem that long ago when I thought I was doing well at 1 KBps with a 14.4K modem ;\

Have a read of this. http://www.webattack.com/dns.html This is where I obtained my thoughts. Also, with advertising sites, you get a lot of cookie servers that want to transfer their files. In addition, I have turned of the default DNS Client, because, I use a very large Host file which minimises the number of connections to these sites as well.

Most users use The Vole's IE because this is the default. Mozilla/Netscape, Opera and others are also available, but do not have the desire to change.
