Micro-optimization for drawing base entities

[noaccessl]

Replaced self:DrawModel( flags ) with Entity.DrawModel( self, flags ).

Makes it ~26% faster.

Benchmark

local Entity = FindMetaTable( "Entity" )

local SysTime = SysTime

local TOTAL1 = 0
local TOTAL2 = 0

local NUM_CALLS = 0

function ENT:Draw( flags )

	do

		local START = SysTime()

			self:DrawModel( flags )

		local END = SysTime()

		TOTAL1 = TOTAL1 + ( END - START ) * 1000

	end

	do

		local START = SysTime()

			Entity.DrawModel( self, flags )

		local END = SysTime()

		TOTAL2 = TOTAL2 + ( END - START ) * 1000

	end

	NUM_CALLS = NUM_CALLS + 1

end

timer.Create( "base_anim:Draw", 0, 0, function()

	local AVG1 = TOTAL1 / NUM_CALLS
	local AVG2 = TOTAL2 / NUM_CALLS

	local PERCENT_DIFF = 100 - ( ( AVG2 * 100 ) / AVG1 )

	print( Format( "base_anim:Draw called %i times:\n\tEntity.DrawModel is %.2f%% faster than self:DrawModel\n\t(%.4f ms compared to %.4f ms)", NUM_CALLS, PERCENT_DIFF, AVG1, AVG2 ) )

	TOTAL1 = 0
	TOTAL2 = 0

	NUM_CALLS = 0

end )

P.S. Changed to using the model drawing function directly.

Isn't it easier to do ENT.Draw = Entity.DrawModel?

Yeah, you're right. Thanks.
