No. The number of processes requests in unchanged. They are just dispatched between 2 instances: the new one and the old one. Actually, all new requests are going to the new instance, and only the pending requests are processed by the old instance.
- nijave 4y agoSure but most applications need a certain amount of memory regardless of the amount of requests they're servicing
