Ways to run net runners that doesn’t monopolize time?

We have started a cyberpunk red game and one of our party is a net runner. However we have found the game slows down while he is doing his thing. It doesn’t seem to be the players or DMs fault it is just the nature of the mechanics of hacking to allow us access to somewhere, get information out, turn off alarms or cameras or take control of the systems.

It can result in a 10-15 min break while the DM and Netrunner make all the various rolls and decisions. If there are 3-4 hacking attempts in a session this can eat up slot of time. It isn’t just us that feel this the DM and Netrunner are also conscious of the fact.

Is there a way to streamline this at all? Our netrunner has suggested writing an app linked to roll 20 that the DM can use to set up hacking challenges so the net runner can then sit and do it by himself while the DM carries on with the rest of us. But are there any suggested mechanics or ways to speed up net running?
