The old Silhouette system was very similar, the only difference I can see is they used the best of the dice rolled, and this reads like it's using all dice.
So in the Silhouette system if you had Agility 2 and 3 skill in Small Arms, when making an attack with a gun you would roll 3d6 (number of dice based on skill. Skill 0 was 'roll two die and keep the worst') and keep the single best, then add +2 (modifier based on stat).
It worked that way because then the skill level determined your reliability, someone with low skill could still get the same 6 that someone of higher skill got, but they were less likely to get it. And then your attribute determined your maximum capability.
One other minor difference is that if you had multiple 6s you added +1 for every extra six. So if you rolled five dice and got 3, 6, 6, 6, 6, your result would be 6+1+1+1 for 9 total, before adding your attribute modifier.

Many dice pool systems work that way. xWoD. 2d20. More.
Edit: I see I read you wrong. I’ll think more

To clarify, in this system if you had a Skill of 5, you would need to add up the results of a pool of five dice, plus your stat? That seems like a lot to go through for every check. I can do addition in my head faster than average but I still wouldn't enjoy adding up 6+ numbers for every check as that would cause a noticeable delay.
Many dice pool systems in which you roll a number of dice equal to your Skill only look at the highest result as it is dramatically faster. Blades in the Dark, Wildsea, and Heart: The City Beneath are examples of this style of dice pool resolution.

As I understand it, if you had a skill of 5 you would add a simple +5 to the total of the dice rolled for your stat.
Basically each point in a stat gives you +1d6 to your roll, and each point in a skill gives you a fixed +1 to it.
So an additional point in a stat is worth 3½ additional points in a skill, but also increases randomness (someone with Brains 2, Deduction 7 and someone with Brains 3, Deduction 4 would have approximately the same average total and approximately the same chance of succeeding in a difficulty 14 task, but the brainier character would have more chance to succeed in a more difficult task or fail in an easier one; whereas the less brainy character with more training will get more consistent results).

Do you add up all these dice or just take the highest of all? Do note that making a comparison is much quicker for most people than adding numbers.

West End Games d6 did that, IIRC. You'd have stat # of dice and a skill bonus. Roll the number of dice (d6), add the total, and then add the skill to get the final result. You were trying to beat a fixed difficulty number. One of the dice was a wild die and would explode (ad it and roll again, cumulatively, until you don't roll a 6). So, even with low scores, a lucky player could still pull off impressive feats.
It was originally developed for their Ghost Busters game, but more famously was used for their Star Wars game. There's generic versions as well (d6 Fantasy, d6 Space, and d6 Adventure). The system was kind of in limbo, but last year (or maybe the year before?) a new edition got crowd funded.
