Which is more efficient?

SetConVarInt(FindConVar("mp_waitingforplayers _cancel"), 1);

ServerCommand("mp_waitingforplayers_cancel 1");

I've always seen it recommended not to use the ServerCommand where possible. The ServerCommand is delayed by 1 frame or something. You can use the ServerExecute command to process the command buffer. If you are setting many cvars eventually the buffer will be full and not set those truncated.

Best method:
Put FindConVar in OnPluginStart and store the returned value in a global handle. Then use SetConVarInt with that global handle. FindConVar is expensive and should not be used any where else except in OnPluginStart().

Thing is, this will only be done once per round, and that's the only cvar I'm setting. I don't care if it's delayed by one frame.

SetConVarInt + FindConVar is considerably faster, more efficient and more "correct" than using ServerCommand.

Alrighty then, thanks Fennec Fox.

Like asherkin said, of course SetConVarInt is more faster and reliable, this call will update the server's engine instead of sending a server command which is going to be parsed then executed.
