%YAML 1.1 --- # Suricata configuration file. In addition to the comments describing all # options in this file, full documentation can be found at: # https://redmine.openinfosecfoundation.org/projects/suricata/wiki/Suricatayaml # Number of packets allowed to be processed simultaneously. Default is a # conservative 1024. A higher number will make sure CPU's/CPU cores will be # more easily kept busy, but may negatively impact caching. # # If you are using the CUDA pattern matcher (b2g_cuda below), different rules # apply. In that case try something like 4000 or more. This is because the CUDA # pattern matcher scans many packets in parallel. max-pending-packets: 2048 # Runmode the engine should use.
