Description

Hi!
I faced with problem when using python graal. When i create context

Context.newBuilder()
.allowHostAccess(HostAccess.newBuilder(HostAccess.ALL).build())
.engine(ENGINE)
.allowAllAccess(true)
.build();
and then get python bindings
Value js = context.getBindings("python"); it takes about 5 seconds.
All times when i create new context and call getBindings it takes a lot of time.
In case of creating Context and calling context.getBindings("js") for javaScript it can take few seconds on first call but it executes less than second on another ones.
I use both JavaScript and Python scripts in one microservice. Docker image based on oracle/graalvm-ce:20.0.0-java11. Installed packages are llvm-toolchain-installable-java11-linux-amd64-20.0.0 and python-installable-svm-java11-linux-amd64-20.0.0.jar
Is it possible to work with python as fast as javaScript?

Research direction

Start with the Context.newBuilder() setup and the context.getBindings("python") call described in the report, using the GraalVM 20.0.0 Docker image and installed Python packages. Compare repeated Python binding calls with the reported JavaScript behavior and measure startup times. Done means the source of the delay is identified and the Python binding latency is improved or clearly explained.
