I have a site which has 400,000+ users and one of the fields of one of my users tables keeps track of the users last activity as a timestamp.  Every time a user does something on my site, that timestamp updates to keep track of their last activity, the problem is, the query that updates the lastactivity field can take a while, up to 4 or more seconds.

Are there any good ways of going about updating a timestamp?  My table is InnoDB and my database is MySQL.
