How are your sessions implemented? Are you using the stock PHP session functionality or did you cook your own solution? I can't see the stock PHP solution adding anything more than a split second to your page time. The exception being when it performs cleanup. Cleanup should be relegated to a cron job. Have you added anything new to the database? new query perhaps on a large table that doesn't make use of indexes? Small changes can have a bigger impact than large changes depending on what exactly changed.
