Hi... I see that no one has answered your post in almost 24 hours, so you may want to provide some additional details to clarify the problem you are encountering. Honestly, your post is somewhat vague IMO. Is it your AutoIt script that is eating too much CPU/RAM or is it Chrome? Give some details on the CPU/RAM usage and why you think it's too high. Are you opening multiple tabs? Which website(s)? etc.
