Performance issue - Githubissues

I tried to make a neon effect for platforms that are supposed to move. For that, I chained three effects and tested a basic motion. Code is bellow. When I run my test, the motion is slow and not smooth. Maybe I do something wrong...

moonshine = require('moonshine')

function love.load()
  y = 0

  blueNeon = moonshine(moonshine.effects.glow).chain(moonshine.effects.fastgaussianblur).chain(moonshine.effects.godsray)
  blueNeon.godsray.exposure = 0.2 --number between 0 and 1
  blueNeon.godsray.decay = 0.8 -- number between 0 and 1
  blueNeon.godsray.density = 0.05 -- number between 0 and 1
  blueNeon.godsray.weight = 0.9 -- number between 0 and 1
  blueNeon.godsray.light_x = 0.5 -- number
  blueNeon.godsray.light_y = 0.5 -- number
  blueNeon.godsray.samples = 30 -- number >= 1
  blueNeon.glow.min_luma = 0
  blueNeon.glow.strength = 5

  yellowNeon = moonshine(moonshine.effects.glow).chain(moonshine.effects.fastgaussianblur).chain(moonshine.effects.godsray)
  yellowNeon.godsray.exposure = 0.2 --number between 0 and 1
  yellowNeon.godsray.decay = 0.8 -- number between 0 and 1
  yellowNeon.godsray.density = 0.05 -- number between 0 and 1
  yellowNeon.godsray.weight = 0.9 -- number between 0 and 1
  yellowNeon.godsray.light_x = 0.5 -- number
  yellowNeon.godsray.light_y = 0.5 -- number
  yellowNeon.godsray.samples = 30 -- number >= 1
  yellowNeon.glow.min_luma = 0
  yellowNeon.glow.strength = 5
  yellowNeon.fastgaussianblur.taps = 9
end

function love.update(dt)
  y = y+50*dt
end

function love.draw()
  blueNeon(function()
    love.graphics.setColor(0.17, 0.46, 1)
      love.graphics.rectangle("fill", 300, y, 100, 3, 5, 5, 20)
    love.graphics.setColor(0, 0, 0)
  end)

  yellowNeon(function()
    love.graphics.setColor(1, 1, 0.05)
      love.graphics.rectangle("fill", 300, y+8, 100, 2, 5, 5, 20)
    love.graphics.setColor(0, 0, 0)
  end)
