Not really. If there’s no swap, then at some point programs will just die when you run out of RAM. Once things start going to swap regularly you might notice a slowdown and have a chance to do something about it rather than kill a process unexpectedly.
For server workloads, you probably never want to use the swap, but it’s safest to have it enabled because you don’t know which process is going to get killed when memory runs out. You can monitor for swap usage and tweak your settings appropriately.
