Performance Improvement - Syscalls vs Kernel Bypass #340

Closed Mzack9999 closed 9 months ago

Mzack9999 commented 2 years ago

Please describe your feature request:

The tool uses a single raw socket file descriptor with default buffer size (net.ListenPacket with 4096 bytes) in user space to send out packets. This is slower but useful as the kernel automatically fills up lower network layers in the OSI stack. The performances can be improved by increasing the outgoing buffer size in user space or by implementing kernel bypass techniques (direct system calls or with technologies mentioned in https://github.com/projectdiscovery/naabu/issues/337)
