How to check if ISP throttles VPN?

[wally4u 2]

Hi,

I recently switched to a new ISP and noticed that my speeds suddenly are significantly (10x) slower than with my previous ISP.

How can I check if they indeed are throttling my down/uploads?

 

Old situation I was able to get about 90% of my bandwith both up/down. so about 90Mbit/sec.

Current situation ~8-12Mbit/sec...... I tried switching the protocols and ports without much success.

 

Test I did:

FTP/HTTP/BT download. No VPN ~300Mbit. with VPN ~10Mbit (varies a bit)

FTP/HTTP/BT upload . No VPN ~30Mbit. with VPN ~5Mbit (varies a bit)

Would like to also know this. I am on a similar situation as you but i get a bit better download speed.

If you used the same hardware and devices and the only change was the ISP, it might be throttling/QoS or simply bad peering.

To know which one of the 2 is more likely to be the issue, try different servers and SSL/SSH tunnel methods.

Well, I basically tried all the servers that have a decent ping and minimal load.

Tried changing the ports as well.

These are the results of the internal speedtest:

Automatic: Down: 21.293 Mbit/s Out, 20.574 Mbit/s In (96%), 20MB - Up: 22.924 Mbit/s Out, 20.950 Mbit/s In (91%), 20MB - Date: Tue, 24 Jan 2017 21:51:18 GMT - Buffers: 20MB/20MB - Laps: 3, Time: 68.48 secs

UDP Port 443 Down: 28.270 Mbit/s Out, 25.489 Mbit/s In (90%), 20MB - Up: 22.728 Mbit/s Out, 20.134 Mbit/s In (88%), 20MB - Date: Tue, 24 Jan 2017 21:36:15 GMT - Buffers: 20MB/20MB - Laps: 3, Time: 47.29 secs

SSL Port 443  Down: 10.572 Mbit/s Out, 8.982 Mbit/s In (84%), 20MB - Up: 21.695 Mbit/s Out, 21.689 Mbit/s In (99%), 20MB - Date: Tue, 24 Jan 2017 21:42:48 GMT - Buffers: 20MB/20MB - Laps: 3, Time: 78.33 secs
SSH Port 22  Down: 18.299 Mbit/s Out, 28.248 Mbit/s In (154%), 20MB - Up: 22.900 Mbit/s Out, 21.296 Mbit/s In (92%), 20MB - Date: Tue, 24 Jan 2017 21:48:05 GMT - Buffers: 20MB/20MB - Laps: 3, Time: 57.44 secs

 

No VPN: Speedtest.net  Ping 10ms. Down: 298Mbit/Sec  Up 29Mbit/Sec (basically max my modem can do.)

 

Any suggestions, to check peering?

Well that sucks. They shut it down on February 5th.

Found diffprobe as another option based on the M-LAB platform.  Difference is that it's an executable to download and run; might not be folks preferred option.

[wally4u 2]

Well, diffprobe only give servers occupied (Tried many times).

Other suggestions?

Simple but practical test would be downloading some popular Linux torrent with VPN and without.

If you see a big difference, like 10x in your case, then you can assume your ISP is throttling VPN.

I wish all torrents had awesome peers like the Linux distro's; always get amazing torrent download speeds.  I recently decided I will always download a Linux distro as my VPN/Torrent test.  Previously I would have just use some other "random" file I planned to d/l anyway, where speeds/peers often sucked, making it a bogus test.  I d/l a Linux torrent a reach full-speed in seconds!

 

Sorry if I am getting off topic, but is there a crappy_peers = OFF setting I implement somewhere?
