I'm tryng to stress a web server with requests, I used
vmstat to get the memory usage of the server, but I don't understand few things.
- When the requests start, the free memory decreases and the swpd increases, but after a while, even if the requests continue at the same rate, the free memory goes up. I think it's because the system goes out of free memory, or at least to avoid that before it's to late, allocates new memory with swap memory, am I right?
- Is there a way to limit the swap memory allocation?
