Isight - so much time and cpu Abaqus get ready to run a job

Dear Abaqus users

I am using Isight and Abaqus for data matching. At the beginning of every loop of my dataflow when Isight want to run my inp file, It take too much time and cpu until Abaqus get ready to run my job. Is there a way to keep Abaqus opened during the entire of the dataflow so the initialization dose not take time and cpu in every loop. Thanks
