Hello I am looking to run imacros with firefox in linux. I want to run like 100 instances or so maybe 1k instances if possible. offcourse in vmware I want to restart linux after every 3 hours and start imacros on every startup. I am looking for a linux which take less ram and i able to run 100 instances at the same time . I only want to run firefox (with imacros ) and nothing else. I can pay too for the right advice.
