Re: database/internet lag?

Sorry, I wasn't too clear in my earlier posting...

I'm wondering how distance between servers affects database replication... I'm assuming typical database replication involves large amounts of data, leading to few TCP/IP connections being made, and lots of data being sent across each connection. So, would a Paris-London replication be much faster than a London-California replication??

I ask because when downloading large amounts of data over HTTP or FTP, distance usually seems to make no difference to speed.

Thanks again,
John.
