Hosted Piwik Location - does it matter?

I recently started to offer a Piwik as SaaS and my question to the community here is:

If you were a potential client, would the location actually matter for you?

Example: You have your site hosted in the US and the Piwik server was located in the EU or the other way around.

Would those extra milliseconds in load time matter? If you were looking as a potential client, would you prefer a location at the same continent that your site was hosted?

Reason I'm asking is that I "need" to know if I should get a second location. For those who are interested the current location is Milan, Italy.
