design principles - Is it recommended to Upload/Download large file through API Gateway?

Question

I have a REST API implementation which has few endpoints that uploads/downloads files, the API's are exposed through the API Gateway (On-premises WebMethods gateway), the size of this files varies between few KBs to several Megabytes. In performance testing i noticed that the Gateway induced about 40% performant degradation, and searching for the reasons led me to few links related to Amazon API Gateway limiting payload sizes to 10MB - i am not sure if this limitation is specific to AWS Gateway, or, a generic limitations across various API Gateways (as part of best practices). I have below questions related to API Gateway:

1. Should large file (size?) upload/download be avoided when using API Gateways? Or, should file upload/download be completely avoided through the gateway?
2. How to handle REST endpoints that supports Multipart/form-data?

Thanks.
