OK, faster for who?
If you read/write them to a database, then it's (slightly) faster for the
client
If you read/write them to a cookie, then it's (slightly) faster for the
server
Remember that for a database access, if you have a separate database server
(which I'd hope you have for a cluster), then the extra work is on the end
of the database server, also, you may have to wait for the data to be
updated - depending on the traffic you put to the database server (and how
your SQL is written, the hardware of the database server, etc. etc.) - I've
seen a delay on my database server of over 20 seconds when the traffic was
(extremely) high...
With a cookie, you know the data is ALWAYS going to be the very last one you
wrote - UNLESS they have disabled cookies, in which case you can't use the
cookie route at all...
