Yeah, the worker is created every time you do new Thread
. Then any postMessage
calls re-use it. It only gets removed if you explicitly call thread.terminate()
. The cost is pretty huge to create the worker though (enough to justify Facebook building the Hermes JS engine)
from react-native-threads.
You've got the cost to start up a new JS VM, parse the additional source code (+ parse the RN source code again), send the contents from your main JS process to the new one, and send it back.
Can you not use native code to do the decryption?
from react-native-threads.
Yep that's what I went with
from react-native-threads.
Is there a one off cost to constructing the new JS VM? ie is the worker re-used for subsequent calls?
