We have a scan engine in Azure and on a VMWare stack. Both provided by Rapid7 (Azure marketplace/VMWare template). Both run on Ubuntu, have 8 GB mem and 4 cpu’s. However, if I issue the ‘free’ command from the CLI I see a big difference,
Azure:
total used free
Mem: 8130056 5818644 158988
VMWare:
total used free
Mem: 8093504 3228092 2735912
Can anyone explain why this is. I’m not aware of a setting that can influence the memory allocation on an engine.
