Very slow scan #52

Closed gitxmax closed 5 years ago

gitxmax commented 6 years ago

Having issue with the scan speed, tried on 4 different servers, but the story is the same, Sample: evilscan xx.xxx.xx.0/24 --port=1-10000 --concurrency 5000 --progress every 1% takes about 2 minutes to scan, --concurrency value doesn't seem to have any effect on the speed. Tried "ulimit -u unlimited" command, with no positive result either.

Probably. If you need the ultimate speed scanner, take a look at https://github.com/zmap/zmap

Same issue, I was thinking of using something like this for detecting microservices when developing locally, but it was too slow. This one was much faster: https://www.hacksparrow.com/a-port-scanner-in-node-js.html or even https://github.com/baalexander/node-portscanner...
