RCU is optimized for the read case and so writes can be very slow.

Writes can't be very slow. Garbage collection of prior copies can be significantly delayed.

The closest thing to writes being slow is that you have to create an entire new unit so having huge units leads to having to copy the full unit in order to make an update. If that makes your writes slow, then you probably need to split that huge unit up.
