vagabond - where do you need fast speeds to? Inside Vietnam things are going to be a lot faster than they are long haul (US, for example).

Also, do you mean kilobits (Kb) or kilobytes (KB)?

If it's the latter you're doing pretty well already, if the former, not so much.

In my experience, FPT is the best provider of ADSL and probably best overall ISP (though I only have indirect experience of that). That evaluation is subject to change, though as things are evolving fast.

On a regular home DSL account with them I get average 40 KB/s (320Kb/S), and their business accounts seem to do better (60KB/s).

I don't actually know how much better than that you can get by throwing more money at it - infrastructure here is a weak point for sure.

HTH,

If you are a user you won't get much better than you have but if you are a service provider i am sure you can get better pro connection in a data center though i don't know which company...

Another thing is here IPS's throttle certain protocols (e.g. streaming media, HTTP, ...) and sometimes specific ports. Thresholds are scheduled and you'll get different speeds throughout the day (Peak/Off-peak hours).
That's why you can sometimes, let's say, get downloads at 128 Kb/s (Really fast) and you still can't watch a video at YouTube continuously and even pauses between breaks are long.

Besides everything that comes in and goes out of the country passes through MANY filters and firewalls, and yes, of course, unnecessarily. Ah! I almost forgot to mention that they really overdo it with the checksums in here.

All of this altogether makes internet speeds pretty lousy.

There's more I can add, but perhaps this is enough. :-)

Good luck!
