O(1) doesn't mean constant, it means bounded by a constant . An algorithm can be faster with small n and converge to a horizontal asymptote as n goes to infinity, and it would still be O(1). In a real machine there is no infinity, but

> 512GB is a huge block size for bzip3 Sorry! That was a typo, it should have been 512MB (now fixed). Still huge.

The benchmarks are disingenuous, to the point of looking cherry-picked. The block size for bzip3 is set to 512MB, but the window size for zstd is left to its default (8MB I believe for high levels). So in this corpus, which is made up of al

In Linux everything is XOrCrash, since allocations never fail but the OOM killer can get you later.

This is a great article but it goes into a lot of detail that can be intimidating at first. For me, the reading that made asymmetric fences "click" is this: https://pvk.ca/Blog/2019/01/09/preemp

Yeah the number sounds a lot less impressive if you say that you only get 2^61.44 integers out of 2^64. In other words, a 4% entropy loss. Information quantities are more meaningfully expressed in number of bits.

That's a false dichotomy: you optimize both the application and the allocator. A 0.5% improvement may not be a lot to you, but at hyperscaler scale it's well worth staffing a team to work on it, with the added benefit of having

It's not just that zeroing got cheaper, but also we're doing a lot less of it, because jemalloc got much better. If the allocator returns a page to the kernel and then immediately asks back for one, it's not doing its job wel

Here RE2 does not fall back to the NFA, it just resets the Lazy DFA cache and starts growing it again. The latency spikes I was mentioning are due to the cost of destroying the cache (involving deallocations, pointer chasing, ...)

> are there eviction techniques to guard against this? RE2 resets the cache when it reaches a (configurable) size limit. Which I found out the hard way when I had to debug almost-periodic latency spikes in a service I managed, where a ve
