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
  
• net_compresspackets_minsize default value increased to 1024. This convar now also determines the threshold to determine when a "fragment" (logical game network message, before being broken up into network packets) is compressed.
