Memory usage always high
My memory usage always seems to be running pretty high, between 60 - 80% and my machine has 4GB of memory.. Is this normal or should i be looking for a problem that i might have?
what packages do you have installed ?
That depends on where the memory is being used. Free memory is wasted memory. The system will use a lot for caching, buffers, etc, etc.
Run top for a few minutes and look at the various memory counts there.
Yes using squid. I have it basically setup as a firewall with just squid and captive portal in use
If you are using squid this is normal.
I have 4GB RAM and when I run squid form some days there are 75% RAM in use ~ 2.2GB only for the squid process:
SQUID uses RAM for the index of your "Hard disk cache size". (I use 10240 ~ 10GB)
Its dependent on the "Memory cache size" (I use 1024 ~ 1GB)
and it is dependent of the "Maximum object size" (I use 524288 ~ 512MB)
