What is - Throttle speed vs Download speed

Photobucket

So many of you are confused of what happen to your connection, why do i register a 384kbps service but i only got 48kbps when downloading? I've checked with speedtest it shows almost 384kbps but why i still get 48 kbps?


So here are your answers

Throttle speed is the speed of you connecting to your ISP (internet service provider - the company you register to).

Download speed is the real speed of your internet connection.

So what is the problem?

Some ISP provide premium internet services (especially for business) and general services. So premium services will get download speed to the maximum (same as the throttle speed) while the general services shares in a ratio set by the ISP for example a 384kbps is shared to 8 users so (384 divide by 8) = your download speed is 48kbps!

Tweak your internet connection to be faster - simple method

You have two ways to make your internet connection faster.

1st is by tweaking your packets settings (which is not very effective and sometimes will make your connection slower, it is because the irregularity/consistency of the download speed, while also because of setting not suited to the connection - why? read more therefore its better to leave it to default setting.

Note that some will gain better connection in term of pings (connection strength between two parties - google for more info) and download speed. So for people who would like to try i suggest an auto detecting software like auslogics boostSpeed. and weird enough for adsl+ users like me the Lan (10/100 mbps) setting provide the best result - because probably you're main connection goes into modem and not the Lan




2ndly, it is by tweaking the half-open limit of your OS

To make your internet connection faster you need to tweak your half-open connection limit (sounds familiar? - yes especially for those who do much file sharing on torrents and p2p).


So what is half-open limit?

Windows XP SP2 and later versions have only limited 10 concurrent half-open outbound connections.
After 10, new connection attempts are put in a queue and forced to wait.
Thus, the speed of connection to other PCs is limited (for eg: on bittorrent you can only connect up to 10 people per sec, 1 min = only 60 people while if it is tweak to for eg: 100, you are able to connect to 600 people in 1 min).(Microsoft do this to slow the spread of virus and reduce DoS attack which is not useful if you got good security installed)

To simplify, it means when search for images , you can only load up to 10 images at once.
If there's 20 images, you need to wait another 10 images to finish then only it load.
For torrent download, you can only receive connection up to 10 seeds/leechs.
When playing games, for eg: DotaA/games which already connect to 9 players others connection with higher priority like antivirus update or download will interrupt, thus slows your connection.

To solve this, simply change the value to 256.(Recommended Value for all types of connections)

You can tweak the value to be higher but it depend on your download speed, not your throttle speed. Do note that Throttle and download speed is not the same.

Why my laptop/ netbook battery drains very quickly?



Why and suggestions:

1)for old laptops without li-ion batteries, do not charge your battery when it's capacity is more than 50%, this reduces your battery life (hardwares keeps memory of battery life and thought that your battery is fully charged). It is recommended for you to drain all the power until about 5% before recharging.

2)Remove your battery if you planning to run your netbook/laptop on power. Continuous charging reduces the battery life cycle (more specifically recharge times/shelf life and will result in a replacement of new battery (which is not cheap :) ).

3)Lower your display backlight and power settings, you can do it at the control panel-> power options/management. These not only will extend your battery life but also the panel/display life, select maximum battery plan for the best.

4)Took off additional RAMs/memory (2GB recommended - mind the data rate, 1GBDDR2 is like 2GB), for the non gamers a lap/nettops with memory of 2GB is sufficient enough for daily usage and extremely helpful in power conservation.

5)Turn off unnecessary/unused devices such as bluetooth, wifi, keyboard backlight and cooler fan (low cpu usage only eg: surfing and downloading only)

6)Turn off virtual memory at my computer->properties->advanced tab->settings->advanced tab (this is for XP google for other Systems) as it uses the hard drive regularly and consume power.

7) Putting your computer on standby is not recommended as it still moderately consume power and its better to hibernate or just turn it off.

8)Use a headphone instead of the built-in speaker(the speakers are bad for the ears anyways)

9)Send your netbook/laptops for cleaning once a year. A clean rigs uses less power as the fans inside it are not clogged with dusk and spins easier without using more power.

10)Do not watch movies or use your optical cd/dvd/bd drives when you're strictly on battery mode because they are power hogs which consumes more power than your hard disk

11)Uninstall unused/junk software and defrag your hard disk regularly to lower the spin numbers thus reducing power usage

12)Update your windows so that your operating system runs more smoothly reducing cpu usage and power.

13)Clean the contact of your battery to prevent dust and oxidised layer so that the battery can run in full potential

14)Choose the right processor/rig!!! for people who low in cpu demand eg: surf the webs and downloads only especially students netbook is highly recommended as it's processor is built specially for these situations.

For advanced users:(not recomended for heavy printer users as it have a bug - make printer offline after a period of time)

u can increase the USB polling so that your computer refreshes/checks your USB devices in a time interval(in ms) decreases. Click link below to learn how to do it.
