Thank you ... but (response here because I needed to add a pic)
- I don't see the entry "External REST WebService"
![alt text][1]
- According to my profiling during 60s of "load testing" it turns out that Ivy spends like 15s reading from the socket / RestClient. Actually I wanted to provide evidence if this is really the case. So it's not about "slow" it's about how much data has been transferred during those 15s. Getting the transferred amount of data would be perfect. Also it is not possible to log on the "receiver" side, because it's all localhost and there are other systems calling the "receiver".
