You can use cachemgr to get a feeling of how much the helpers are used. If you go to the basig authentication helpers screen you will see each of the helpers instances listed and the number of times it was used. Most likely you will find that only the first three or so have been used... There is no huge penalty from having too many basic auth children started. Costs only a little memory for the helper program and a filedescriptor for Squid.. Regards Henrik
