Interesting, sitting with a finless server with
Intel(R) Celeron(R) CPU N2940 @ 1.83GHz
Current: 1826 MHz, Max: 1827 MHz
4 CPUs: 1 package(s) x 4 core(s)
AES-NI CPU Crypto: No
QAT Crypto: No
With 8GB RAM
With Siricata running I wasn’t 100%CPU utilised and 100%RAM utilised.
Having disabled it it dropped down to 60-70% on CPU and 60-80%% on RAM.
the 100% utilisation actually caused network slow down.
