1GB of RAM and I have about 50 devices in the NAV seed database. I've noticed that almost all the the memory is already in use. It's no problem for me to increase it since it's in a virtual environment. But since I increase it I was just wondering if this is normal for NAV to use such amount of RAM memory.
Hi,
There are very few server applications I would run on a single GB of RAM these days, NAV included.
The current NAV virtual appliance ships with a setting of 2GB RAM, which is an ok minimum, I guess. This is also the amount of RAM in our own VM-based production instance, monitoring our modest internal network. Of course, all of that memory is also constantly in use, as the OS will use whatever free memory it can get its hands on for buffers and cache.
We also run production servers that come standard with between 12 and 16GB of RAM. These also rarely have any free memory - because the OS will fill it with buffers and cache. The lesson being that you should add up the numbers for free, buffers and cache memory to see how much you really have to go on.
