The Express Lane is a priority request queue that makes LiveJournal faster for Paid and Permanent users. When logged into your Paid or Permanent Account during times of heavy site load, your requests for LiveJournal pages are sent to the web servers before other users' requests.
LiveJournal's main priority as a service is to offer all users, Basic and Paid alike, fast and uninterrupted access to the site at all times. LiveJournal's fast and numerous web servers ensure speedy access most of the time; however, like any service, LiveJournal does encounter unavoidable periods of heavy site load. The Express Lane is designed to speed access for our paying users during peak times.
Load Balancing & Queues
Even with more than two million active members, it can be hard to imagine that LiveJournal.com displays tens of millions of dynamically-generated pages each day. For these pages, a LiveJournal technique called "load balancing" sends your request to the web server with the fewest requests.
During times of heavy site load, all of LiveJournal's web servers are too busy to accept new requests; then the load balancers begin a queue of requests. Requests at the beginning of the queue are sent to the next available web server, but new requests are added to the end of the queue, where they wait in line.
