@mhuebert did you ever experiment with running the compiler in a web worker but eval in the page? that would probably solve all performance concerns at the cost of slightly higher memory usage

I modified my test impl to use a webworker to run the self host compiler, this offloads all the “slow” stuff to the worker

eval happens in the worker as well as the “host”

could be optimized a ton but seems to have far better performance

although it still locks up just from the eval, so overall its probably not worth it

No, i hadn't tried that. Wasn't sure how complicated state sharing between the two environments would be

Or if only passing compiled strings is sufficient

If a compiler state atom still available in evaluating, or if it needs to be

At ClojureBridge today so not much time

if you need access to the compiler state then web worker is not great

forgot that the maria editor might need that

I guess depends on how big a difference it makes to performance. Does evaluation need to happen in the worker at all? Introspection maybe can be a special case

Have to try that and see.
