got to agree with a lot of the posts - deckkers take up a one to one isolated session for them to do stuff in the matrix - a solution could be to hire one in who will do their dekker thang remotely from the safety of the hotel room via some device the player runners cart around with them
This is something I keep seeing, personally, it just doesn't match my experience. I'm not accusing you of exaggerating or making anything up, mind you. It's just from where I'm sitting, the whole "other players go out and get pizza while the GM and Decker do the matrix minigame one-on-one" strikes me as a meme held onto since earlier editions and doesn't hold much weight in 2080 (we are up to 2080, aren't we?)
I'm not going to say Deckers are now integrated perfectly and there's never a time when a decker is the focus for an extended period. But the decker minigame just doesn't exist in my games, not like when deckers had to do a literal dungeon crawl every time they jacked in. Now it's more like when the rigger is spending time doing recon and sneaking their fly spies around, or when the Face is taking the lead in a meet up. It's just that character getting their spotlight for their speciality. That's normal and expected.
And a decker can't really do the remote dude-in-the-chair schtick anymore. Even if you can deal with the noise, which isn't usually that hard, the ubiquity of hosts means anything worth securing can have a Firewall of 10+ without much difficulty. If what you want is in the host itself, you're going to get opposed rolls that quickly outclass deckers in raw numbers. It is always better for a decker to get up close and plug into a slaved device. Runners should always look to come at a problem sideways and for deckers, that sideways is usually to get out the wires in your wireless world. But for them to do that, they frequently need other team members to help them, so not only does 5e bring deckers into the field by necessity, it brings other players into the matrix run. The sam can give them cover, the infiltrator can find them access, the Face can be a distraction to buy time.
Yeah, I've had sessions where the decker takes up a big chunk of time on their own to do some legwork and I've worked to try and reduce that a little more. But it in my games, it's just not the problem other people claim to have.
Glad its working out well for you. I have to ask, what are to doing to speed up all the required checks? Even something as simple as hacking a maglock directly has several rolls involved... Going through a network to hack a mag lock as several more rolls....
Now I fully agree the game has done a lot to speed up a lot from 3e and back.. but it still has a ways to go. And the other side of the coin is for some its not as rewarding as the other roles..
For example: your team comes into contact with a group angry gangers! What do you do!?!?
Pass 1:
Mage: I blast them with a fireball!!
Rigger: I command my drone swarm to lay down multiple zones of suppression fire!
Sammy: I Multi attack several with my Assault rifle!
Decker: I begin looking for hidden marks, so NEXT pass I can begin to hack, and then maybe the next round; Brick a gun!
Pass 2:
GM: "well, everything's dead"
Mage: I start scrubbing my aura!
Rigger: I send the drones out to recon the area!
Sammy: I reload
Decker:.... I hate my life.
Deckers/technos can be annoying in combat - ask any sammy that's had a gun bricked. (and Ask the Sammy how good it felt to beat the decker to death with the bricked gun! Its part of the story too 
)... But they don't offer that immanent gratification that other combat options have...
Heck it is for this very reason, "decker arm of doom" is a trope... because "Why deck when I can shoot! And I STILL get to deck when the door needs to be opened"...
The biggest change I made was to make most decking rolls a threshold and not opposed. I can calculate results much faster and keep things moving. It is a little but noticeable difference.
Combat is a bizzare metric to judge how rewarding being a decker is. It isn't what they do and that is fine. Combats are usually over in a couple of turns and if the decker spends that time playing digital poker with the face and driver, while your samurai, drone rigger, and combat mage do the murdering... Okay. Seems fine to me. I would suggest players who want to kill stuff be physical adepts, not deckers. That said, if the runners are doing the job right and ensuring all combats are on their terms, the decker should be getting their MARKs before initiative is rolled for a fight. In my campaign, fights often start at the decker's signal. The physical team gets into physical position and the decker gets into digital position. The decker feels a lot less left out a and useless in combat when the run is going well. And if the run is not going well, nobody should feel good.
In any case, a more interesting comparison is the maglock, which can be resolved by similar non-combat types. There is one roll to open the lock casing, all would-be thieves must do this. Now a locksmith rolls to unlock the lock that is an extended test so is one or more rolls. A decker rolls to place a MARK and since the lock likely doesn't have a rating higher than 4 (and that is a good lock) a competent decker likely doesn't need more than one MARK, so she now rolls to Control Device and open the lock. In all it is at most one extra roll. Not a big deal.
But it is a huge benefit if that lock was slaved a host. Now the decker has easy access to every lock slaved to that host, and the cameras, and the data, and depending on security setup, possibly the commlinks, drones, and weaponry of security. The decker might now be well placed to get the team out of any fights.
But in this scenario, the samurai role is looking kind of left out and unsatisfying. But of course a particular role will feel out of place when it is... out of place. Sure a Samurai might have a tool for the job but it isn't what they bring to the team.
But stepping away from this idea of being unsatisfying again, and back to deckers taking up time, all of the above successful decking requires a decker on site and they can't be there on their own because they need somebody to at the very least guard their squishy (potentially unconscious) body. And GOD makes it impossible to deck too far in advance. The matrix side of any run must be physically and temporally adjacent to the meat space side of a run.
Some legwork can be done solo, but everybody does some leg work solo. Again, the decker isn't unique.
I readily grant that decking is often still time consuming and it has taken 5 editions and some personal house rules to get to this point, and we can still probably do better, but in my weekly experience, it just isn't the problem I hear about from other people.
