What maximum speed can I expect from using a VPN?
Chris:
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?
daniel.yrh:
thanks Chris, I will email you the logs when I reach home tonight.

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 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)
--- End quote ---
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)
--- End quote ---
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)
--- End quote ---
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)

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..
Chris:
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 :(
