We are using an old m3.large instance which has 20-25 audio streams, and that seems to be the maximum it can handle. When choosing larger instances, is it recommended to opt for a higher CPU to RAM ratio, or higher RAM to CPU ratio? It is difficult to ascertain from the Server Monitoring page.

In general what I’m asking is: does WSE usually want more CPU or RAM per stream?
