How increase abaqus calling and running speed from Matlab

Hi, I run my abaqus model from Matlab code for a GA optimisation operation,but it takes long time to run more model in loop . Is there any solution to call abaqus once and don't close it

Create your abaqus object first. Then pass it around by parameterizing functions; http://www.mathworks.com/help/matlab/math/parameterizing-functions.html
