Commonly used aggregation ratios & how often is RAM oversold?
Just interested in data. What are some commonly used aggregation ratios (number of virtual CPUs per physical thread)? How often and how much is RAM a HDD/SSD oversold? Thanks
BTW: For three commonly used hostings in Czech Republic, the aggregation is usually 1:4 and RAM is usually not oversold. But I know of one cheap hosting that offers way more virtual cores per physical thread than 1:4 and possibly oversells RAM, and the performance during peak hours is just really painful (i.e. the latency in SSH was 1 second during christmas and simple Java Spring + nginx website wouldn't load, really really disgusting).
