I'm using it all the time for string and i haven't seen any performance issue so far.

May be try to increase the buffer :

def stream_to_string(stream,buffer=1000000)-> str:
    string = ""
    stream.Rewind()
    while not stream.AtEnd:
        string += stream.Read(buffer)
    return string

Thanks, but i can't find the Python Adapter do you mean EnsLib.PEX.BusinessOperation or IOP.BusinessOperation.

Next if Embedded Python runs natively on iris, why i have to declare a connection as you mention in your example ?

Does this work best ?

from iop import BusinessOperation

class HelloWorld(BusinessOperation):

    def on_message(self, request):
        self.log_info("Hello World")

wow, nice article, can you provide more information about how you register this python class into a production ?

for the more, can you tell me what is the difference between embedded python and irisnative, i'm a bit confused.
