Hi 
My securesphere have a high memory,top command display the gw.x usage 85%.
I know that linux pre-allocated the memory give securesphere , but i think the memory will freed when the traffic low.
The high traffic increase the mem usage,but after 24h, the memory still very high and keep 90% usage,even thought my traffic just around 200KB.
There are any recommand ,thanks
how long the mem usage will freed ?

Hi Jeff,

For performance optimization, GW mostly uses on startup pre-allocated memory blocks for configuration and traffic flows. This is by design., and the memory usage will not be freed.

CPU usage is a much better indication of load. 


Thanks.
