An update to Team Fortress 2 has been released. The update will be applied automatically when you restart Team Fortress 2. The major changes include:
Source Engine Changes

• Fixed server CPU spikes caused by compression of string tables and packets.
• Added sv_netspike, sv_netspike_sendtime_ms, and sv_netspike_output convars for investigating server performance
