Hello Enzo, 
 The swap memory consumed is normal and if you have started using IPS then the memory consumption would also increase which is well within expectation. As per the usage on the system the SWAP, total memory and most of your memory is cached. 
 
 The image is from a XG firewall with no load and has configured for 2 GB ram. There will be no performance impact and the memory is reserved. As your memory is higher the amount of free memory is less and but they are mostly cached/reserved. 
 The ram management has changed since Cyberoam as in Cyberoam the amount of free RAM will directly conclude the capacity of the machine. when reached 90 to 100% performance issue is observed. In SFOS it is completely different the amount of RAM is reserved at the start and used for your resources when needed. If the system is acting up you may check the RAM impact as the " 0.0%wa," would indicate the amount of process awaits to be processed. Ideally 0 but would be normal >1.0 or 2.0 depending on the model.
