The Good: Pixmap is heavily GPU accelerated. If you have a decent graphics card, you can push grids up to 1000x1000 (one million individual calculations) at real-time framerates.
The Bad: Because it relies on a grid, extremely high-resolution source footage (4K+) will lose fine detail if your grid resolution isn't high enough. Additionally, the plugin works best with hard edges; soft gradients can sometimes produce banding unless you apply dithering to your Driver layer first. Pixmap Plugin After Effects

For color mapping operations, precompute LUTs:
uint8_t gamma_lut[256];
for (int i = 0; i < 256; i++)
gamma_lut[i] = (uint8_t)(pow(i / 255.0f, 1.0f/2.2f) * 255.0f);
// Use LUT inside pixel loop
out->red = gamma_lut[in->red];
