System memory usgae
I have an rp4440 server with 1 GHz * 4 CPU and 10GB memory
I noticed that system memory usage is about 4GB/10GB total memory on glance
Customer asked me to reduce system memory size
Is there anyway to resize system memory size?
I need to explain what root cause is

Re: System memory usgae
I've attached a script for you to look at and run. Can you paste in the values of the kernel parms. listed in this script?

Re: System memory usgae
1. Find the default number of vxfs_ninode
echo "vxfs_ninode"|adb /stand/vmunix /dev/mem
2. Adjust the parameter to 20000 if your machine is not file server
SAM--->vx_ninode=20000
Thanks.
