It can be if your thread synchronization scheme is sub par.

 Another reason to avoid threads.

Why? Believe it or not, there are ways to create _highly_ scalable thread synchronization schemes. Using a global lock is not one of them... :^)
For database servers, RCU is probably the best you can get. It simply shines for read mostly workloads.

So long as your async tasks have an await
call somewhere in their main loops, that should be sufficient to avoid
most bottlenecks.

async tasks are using threads... No? Also, what type of synchronization schemes are they using under the covers? I would hope they are using some efficient lock and/or wait free algorithms. I have a lot of experience in this area.
