Simulate access on different country

Is it possible to simulate the access from different country, say, the server is in US, and I want to test my application's performance from Tai开发者_如何学编程wan, Japan or Malaysia, and my pc is in Hong Kong.

How can I do that? I try use TOR(maybe I'm going wrong, please correct me), but it looks like can't manually connect with different router, and seems the data is transfer like this

my pc->Tor network->web server->Tor network->my pc

however, what I suppose to test is like this

my pc-(vnc)->remote pc<->web server

Please give me some direction, thanks, a lot~!

Rent a VPS for a month, in the country you want to test with.

Or pay someone on rentacoder.com or mturk.com or craigslist.org from those countries to submit test results data to you.
