There are features added in v6 specifically to address this by shimming out the JavaScript functions for native implementations. I plan to get a package up that makes all these shims available, but any help would be appreciates.

For example, the expensive part of .createRandom() is likely the sha2-512 operation, so you can use: ethers.sha512.register((data) => { return nativeImplementation(data); } where nativeImplementation is a function you provide that calls a JNI (or such) implementation.
