I guess that we could create sub-directories. Somebody suggested one directory for each family. Why not?

I've tried to save the syntax tree in a simple binary format but loading this is not quicker than parsing the file. Bison is really good! Another trick: we could parse all the .nasl, and keep all the syntax tree in memory. But this might be too expensive (in MB). >> Over optimizing might be dangerous too: if the web server banner is >> not in the KB because of a network glitch, the plugin should try to >> grab it again (that's what get_http_banner does) > This is silly.

The service detection system tries to warn you anyway: e.g. find_service will say "an unknown service is running on this port, it is usually reserved for HTTP" and then find_service2 ou doublecheck_std_services will detect a web server. You will know that you have a problem, that you should increase the timeout or fix the network. > you end with a partially bogus report The report will be "partially" bogus in both cases. > MS Windows kill TCP connection with RST when the task dies (GPF etc.). Excellent idea! We just have to enhance the API to get the last error code - I guess that nessusd will get ECONNRESET, no? > As far as I can tell, Nessus has always been more memory (*) and network > bandwith hungry than CPU hungry. > (*) Memory leaks might have played some role here...
