Title: What maximum speed can I expect from using a VPN?
Post by: Reuben on August 07, 2007, 12:36:11 AM
Now you may be wondering, how come I don't get my maximum advertised speed even on the well seeded ubuntu torrent?

This faq assumes that you have

a) A perfect line or close to perfect one (good SNR and attenuation)
b) No routing issues with TM
c) No other background programs that use the internet running
d) No seeder/peer ratio issues
e) TCP optimization has been performed

Please check the speed troubleshooting guide (http://www.bolehvpn.net/forum/index.php/topic,61.0.html) if you wish to know how to tune your computer to close to achieving these conditions.

Most ISPs use the PPPoE protocol. This protocol has some overhead which results in around 10-15% loss in effective throughput. This PPPoE overhead is ALWAYS there regardless of VPN or not. Even your HTTP downloads are still subject to this.

Furthermore, the use of a proxy/VPN results in some overhead as well. We estimate this to be in the 10% region.

Now the figures given below are more or less theoretical and is still subject to loss on your ISP's line and I have not even factored in BT overhead or upload saturation.

1024 kbit Line (1 Mbit)

Quote
1024 kbit = 128 kB/sec

Take off PPPoE overhead (15%)

0.85 x 128 = 108.8 kB/sec

Now take off VPN/proxy overhead (around 10%)

0.9 x 108.8 = 97.9 kB/sec (Expected max speed roughly)

512 kbit Line

Quote
512 kbit = 64 kB/sec

Take off PPPoE overhead (15%)

0.85 x 64 = 54.4 kB/sec

Take off VPN/proxy overhead (10%)

0.9 x 54.4 = 49.0 kB/sec (Expected max speed roughly)

1536 kbit Line (1.5 Mbit)

Quote
1536 kbit = 192 kB/sec

Take off PPPoE overhead (15%)

0.85 x 192 kB/sec = 163.2 kB/sec

Now take off VPN/proxy overhead (around 10%)

0.9 x 163.2 = 146.9 kB/sec (Expected max speed roughly)

2048 kbit Line (2.0 Mbit)

Quote
2048 kbit = 256 kB/sec

Take off PPPoE overhead (15%)

0.85 x 256 kB/sec = 217.6 kB/sec

Now take off VPN/proxy overhead (around 10%)

0.9 x 163.2 = 195.8 kB/sec (Expected max speed roughly)

4096 kbit Line (4.0 Mbit)

Quote
4096 kbit = 512 kB/sec

Take off PPPoE overhead (15%)

0.85 x 512 kB/sec = 435.2 kB/sec

Now take off VPN/proxy overhead (around 10%)

0.9 x 435.2 = 391.7 kB/sec (Expected max speed roughly)

I remember reading somewhere that DHT costs another 4kB/s or something like that. However, you get a lot more peers by enabling DHT unless you manage to get a good source tracker.

any one try soho package already? I am a Soho user .

There's little difference between normal streamyx and soho streamyx.

Perhaps better contention rate with soho but even that is debatable.

This means it should work with your SOHO streamyx with no problems as it is basically the same setup.

it wont work if using SDSL rite?

It should work. But not sure if SDSL is throttled.

it would be great if using the new streamyx 4mbps...
could get 0.5MBps...

any one try soho package already? I am a Soho user .

i'm using soho 1mbps.... initially max 120KBPS (after 2-3days connection problem, newbie maaa)... now average 80KBPS... i'm considering it as ok...

i'm a new user of bolehvpn. and i've tried downloading with utorrent, max speed i can get is around 40-50 kBps/sec. but mine is a 1 Mbit line. according to the info given above, i'm supposed to get around 90 kBps/sec. i have used the tcp optimiser n also the patcher and still getting the same speed. is it my internet connection? or is the speed considered ok?
when i download and surf(eg. facebook), the web takes longer to load, am i supposed to reconfigure the firefox settings? as i have read from the blog, i only need to change the config for privacy reasons etc.

any solutions? :)

Thanks!

do the tmnet speedtest
check if tmnet miscapped your speed

download speed 325 kb/sec. upload 106kb/sec. is that ok speed?
Title: Re: What maximum speed can I expect from using a VPN?
Post by: PatrinaY on December 27, 2008, 05:13:12 PM
i still get a speed of around 40-50 kbps/sec for downloading. i have done almost everything, ping average is 487. did tcp optimiser and patcher. my router has network cables that connects to 2 computers in my house. and my laptop uses wireless connection.
i'm at loss...

any advise?
Title: Re: What maximum speed can I expect from using a VPN?
Post by: Reuben on December 27, 2008, 06:11:49 PM
If your download speed shows 325 and 106 that's in kilobits per second. There are 8 bits to a byte. Means 40-50 kB (kilobytes) per second is the max your line can get.

That's TM's fault or that you have been miscapped or that you are having severe problems or the other computer in your house is sucking up bandwidth.

Post by: PatrinaY on December 27, 2008, 06:37:59 PM
i see. well, i guess there's nothing much i can do about it then. i could prob ask tmnet to check the speed in my area, and hope that i can get around it.
thanks for the info!

sorry, one last question...
does changing the modem help?
i'm now using a separate modem and a router.
Was thinking of changing it to the D Link modem+router...
Title: Re: What maximum speed can I expect from using a VPN?
Post by: freeman85 on December 27, 2008, 07:36:38 PM
dont really think so unless your router cant cope with p2p
what u need right now is to call tmnet and complain  :D

anyone having the same problem?  :)

This is an isolated problem for you if you are getting such a low speedtest result.

have a 60 Mbit connection and getting 5+MB/s from it downloading from usenet.

this is 70% of possible speed with an open connection. (meaning not behind VPN) this is quite good.

as a matter of fact this is the fastest i've seen from any VPN service i've tried so far.   :P   (http://th1233.photobucket.com/albums/ff381/crazeyechan/th_1205099zhwi7s2bb3.gif)

Hi Reuben,

I am on 25Mbps cable broadband (from Starhub Singapore, with subscribed International speed at 12Mbps and Upload Speed at 1.2Mbps).
Did a Speedtest and I got close to 12Mbps download speed.

Problem is, my uTorrent running on BolehVPN (proxy mode) only gets 1-2Mbps... by downloading an uBuntu ISO file via uTorrent. When I bypass BolehVPN (remove all proxy settings on uTorrent), I get close to 10Mbps.

Is BolehVPN limiting download bandwidth?

Title: Re: What maximum speed can I expect from using a VPN?
Post by: Chris on November 26, 2013, 04:26:22 PM
No, we do not limit bandwidth. Could you email us at support@bolehvpn.net with your logs from the BolehVPN client and which server you were connecting to?
Title: Re: What maximum speed can I expect from using a VPN?
Post by: daniel.yrh on November 26, 2013, 05:07:13 PM
thanks Chris, I will email you the logs when I reach home tonight.

Hi, I from malaysia.. I'm using tm streamyx with 2mbps package.. does this help me increase the speed of my internet connection? the max speed at my apartment's tm port can support is about 3.8mbps.. as it not bypass the requirement for 4mbps package, then i have to take the 2mbps package only..

Hi there,

If you have a 2 mpbs package, then we can help you unthrottle your speed to the maximum of 2mbps. We cannot make your 2mbps connection turn into a 4mbps connection unfortunately :(
