If some race of people lived for 200 years, would their civilization progress faster or slower relative to the control civilization? Assume no cross-contamination of ideas and comparable periods of youth and senescence (no struldbrugs)

On one hand, their rulers would grow increasingly conservative with age, projecting their influence far into the future. Imagine the Founding Fathers sticking around for the civil war and WWI, explaining what exactly their intent was when they wrote this or that amendment.

On the other hand, imagine one of the brilliant scientists that had an outsized impact on the world. Borlaug, Pasteur, von Neuman, etc. Now give them 120 more years to live. This won't just quadruple their output: now they can collaborate with a much larger cohort of scientists. Building dream teams like the Manhattan project will be much easier.

On the gripping hand, all these long-lived people are going to have sex, validating the worst predictions Malthus had regarding carrying capacity. Who has time for science, unless it's the science of waging war against your neighbors before they do the same to you? Would a civilization like this hit a worse local optimum and be passed by the shorter-lived one, stuck with the sharpest and deadliest stone or copper tools in existence?

On the other gripping hand, elephants and parrots haven't outbred all other birds and mammals. Perhaps the longer-lived people would have evolved into extreme K-strategists even before their discovery of fire or tools?

I could go so many ways with this. On the one hand, it may cause civilization to progress slower. Even now, with all the dying boomers, and their deathgrips on the levers of power, the US seems utterly incapable of meeting the challenges it faces. Their beliefs, and what they think the world is, is just too ossified in their minds. Give them another 100 years, and I can't fathom the hell of stagnation and decline we'd be in. And it's arguable this has been an increasingly severe problem the last 30 years.

I'm just not sure allowing the old blood of a civilization to further fester, stagnate, and stand in the way of the youth is beneficial. I think such a civilization would trend even harder towards some sort of stagnation, like an uncontacted African tribe.
