comment SSH through OpenVPN on iPhone
@GRoNGoR (1) On the iPhone, after VPN connected, in the connection details, is the server name and ip correct? (2) Check your cert file, open with vi, and see if it contain CR (MS-DOS format) at the end of each line. If so, remove them.

@GRoNGoR If ip address stay the same, your traffic is not routing through VPN at all. That explain why you cannot ping vpn server 10.0.1.x ip. I will go though the log.

comment Slower file create on faster server. Why?
(1) Is it possible to change 'relatime' to 'noatime' and run bonnie++ again? (2) Can you get the mount option from /etc/fstab from the old server? Maybe from a backup. That way we can compare the mount option.

comment Reducing the delay occured during DNS change
I did a search about Godaddy Premium DNS TTL minimum, base on a forum post it is same at 30min. But you can should call godaddy to verify.

That really depends. Godaddy does have a huge infrastructure with minimum downtime. However, if you need a dns with low TTL like 1 to 5 min to switch A record quickly, you either have to run your own or find dns hosting (no need to change registrar, but company/service that host dns) that allow low TTL.

Domain registry TTL only apply if you are switching DNS server or transferring from one registrar to another one (eg. switching from Godaddy to another company).

The theoretical max. delay is double the TTL. However, if the TTL is set to a small value, like 1 minutes, then it maybe affect by the minimum time out, like 5min (or 2 to 3 days according to your link), of some dns servers, that will always beyond your control. The domain registry situation does not apply in this situation though.
