@vmoroz @AlexLablaiksSAP would it be possible to obtain a non-ReactNative repro?

@evelant when you say 4x or 6x faster, can you be a little more precise? What exactly is faster? Startup time? Update rate? Do you have a benchmark demonstrating the...

@evelant if you are experiencing 5 time longer startup with Hermes, that is a strong indicator of a systemic problem like running from source instead of bytecode. It is extremely...

According to the error message the total allocated memory seems to be 910163968 + 2560326059 = 3.2GB, which is more than 3GB. So that could explain why there is an...

(BTW, I noticed that this is RN 0.68, which is a version of Hermes that is over an year old, making it that much harder to figure out what is...

Thank you for reporting this. It looks like an actual problem and is likely caused by us not caching the timezone information. As an experiment, we changed the system timezone...

We agree that this needs to be fixed to match the behavior of the other engines. Unfortunately we don't have concrete plans on when exactly we can work on the...

@rpopovici are there APIs for updating the cached timezone information in JSC? In other words, if a RN app is running in JSC and a system timezone change occurs, how...

@rpopovici this indeed looks like an attractive solution. What is the thread safety of the callback, i.e. in what thread will it be invoked? I suspect the safest thing to...

Hmm, unfortunately Hermes doesn't own a thread or an NSOperationQueue. It executes in the context of an arbitrary thread provided by an integrator. Adding functionality like this is never as...
