مزایای استفاده از openvpn نیاز مقابل سرویس دهنده مشتری?

1. Another benefit besides it being open source is you get the latest software/algorithm updates. So a providers client may be faster, but may only be this way because it uses an older encryption algorithm that is less secure.

2. The only reason there’d be a speed improvement by using different software is if the encryption protocol has been weakened.

   I find it very unlikely that a VPN provider would be able to provide custom software that’s simultaneously faster than the biggest open source VPN while being just as secure.

   CPU cycles are CPU cycles, and if a custom client is somehow encrypting “faster”, either some random software guy working for the VPN is an underpaid genius, or the client is skimping out on some part of the encryption process.

3. “It depends”.
   In theory the .ovpn config files you download from the provider should be exactly the same as the config generated by any client software. But.. sometimes they aren’t. For example, you tend to get 1 .ovpn file per exit node while the client software might let you tweak encryption settings. Also but.. that shouldn’t make the kind of dramatic speed difference you’re talking about. Also but.. the client software might use a different version of openvpn or include patches that vanilla openvpn doesn’t have. Again, it’s unlikely that would make the speed differences you’re talking about, but there are some buggy versions of openvpn (which version tends to depend on the OS you’re running it on).

   The kind of speed reduction you’re talking about either sounds like a bug / clash in the openvpn version you’re using with the OS you’re using, or your VPN provider going downhill, ISP throttling VPN or particular port connections, or “unknown weird error”.

4. switching to openVPN is unlikely to improve your speed unless you’re being throttled by your ISP. with openVPN you do get the ability to edit the port your VPN is using as long as your VPN supports other ports.
