Until now the maximum amount of pending requests from studio-client to studio-server was set to six. This limit was given by the use of HTTP/1.1. Nowadays HTTP/2 is used and with HTTP/2 the limit has increased significantly. By default the maximum amount of pending requests is now set to 50 and can be adapted by setting the property rest.network.maxRequests in the studio-server.
