1. Please have a look at page 35 of
our online documentation. The example script at the bottom of the page is set to run asynchronous, LsPush not influencing login times at all.
2. Yes, 40KB is correct for one full scan.
3. Everything is rescanned each time. No Lansweeper settings are taken into account. A connection to the Lansweeper server is not required when using LsPush, so having the executable check settings wouldn't be useful.
4. Could you clarify this question? Active Scanning, IP Range Scanning and LsPush will capture the same information, if this is your question.
