The time taken for a request to complete depends on factors such as:
a) Request Type
b) The speed of retrieving data from the source. This can be limited either by rate limits at the source or in case of in-prem servers, the bandwidth at the source
c) The conversion complexity
d) The speed of uploading data to the destination. This can be limited by rate limit at the destination or in case of in-prem setup, the bandwidth at the destination.
We have seen an average of 1GB an hour as the data conversion and upload speed across all request type.
