I have some experience with Seastar.

Seastar and Silk are both event-driven, thread-per-core platforms with synchronization and scheduling facilities built-in.

Seastar is meant to be an integrated platform so it includes I/O and networking primitives for high-performance storage and socket operations to boot.

Silk does not appear to take an opinion on how the actual work performed on the thread should be architected
