> Reading compressed text files using textio.ReadFromText() is about five times
> slower compared to the corresponding transform in Java SDK. This is specially
> noticeable when using DirectRunner. We should look into how we can improve
> efficiency of this so that Python SDK is more comparable to Java SDK in this
> regard.
