Is virtual memory fast as RAM ? Is it slower / faster than RAM ?

Is Windows virtual memory as fast as RAM or is it slower or faster than RAM ? Do I need to buy additional RAM or is it enough to increase virtual memory ?

Virtual memory is used to supplement RAM memory when needed. RAM memory is much faster than virtual memory. For example, when you have two same PCs, but one is having 8 GB of RAM and the second one is having 4 GB of RAM and uses 4 GB of virtual memory, the PC with 8 GB RAM can provide better performance.

RAM is used for a high speed data transfers. It has much higher speed when reading or writing data than HDD or SSD.
