Relative runtime of ELISa while evaluating the LCs in three different passbands for EB models with circular (solid lines) and eccentric orbit (dashed lines) with the eccentricity of e = 0.2 (see model parameters in Table B.1). The LCs were obtained for different values of the surface discretisation factor and the number of points N on the LC. We then compared the results obtained by ELISa with PHOEBE v2.2 performance on the same benchmark models.
