At the moment a new service session is created for uploading/downloading each verification task and its solution if so. This seems to be extremely redundant. I suggest first to use not more than 4 sessions for that (ideally 2: one in Core and one in Native Scheduler). Since the implementation will likely introduce some gateways, then perhaps it will be also better to upload/download several entities at once if they are available and then to distribute them over workers. Altogether this will reduce a Bridge load and speed up the whole verification process.
