How does chrome deal with this in whatever allocator they use?

I generally find Protobuf the serialization format to have no benefits over JSON. Although Protobuf is often thought of as being faster to process and more compact, the reality is that it's usually not (at least as long as you're

Correct. We do provide a paid service for symbolicating all addresses with the help of dSYMs, though.

What sort of workloads are those? I have yet to see a workload where macOS's system allocator is not substantially slower than alternatives like jemalloc.
129.

Will this have support for macOS by inserting itself, as jemalloc does, as the default malloc zone? If so, does that mean it will be very fast at determining if a given pointer was allocated by libpas?

On the other hand, I think people listen to his views on politics largely because he's well-known as a chess player. In a sense, people do the opposite of an ad hominem attack, by putting more stock in his arguments because of how resp

I'd be really interested to see benchmarks of Apple's allocator versus others, both in memory consumption and performance. Sometimes, Apple's version of things is worse in almost all use cases, but I'll reserve judgment

mimalloc is briefly mentioned in my article, and I was surprised that it worked on the mac for swapping itself in. I found the performance of it to be roughly the same as jemalloc when I measured

Yeah, related to timegm(), I made this to fix a performance issue: https://github.com/michaeleisel/JJLISO8601DateFormatter

What impact does this tire have on car mileage?

It appears that sorting is done on the memory-mapped buffer? That seems like it could have extra costs (lazily paging in from disk) that we wouldn’t see for an in-memory buffer, and which could affect the benchmark.

On top of these design issues, I'm surprised by how buggy the core experience can be. The home page repeatedly failing to load on many different occasions. The site suddenly acting like you're logged out and needing a refresh. It&

Can you provide more examples of this?

Surprising that this isn’t getting more upvotes. It’s a very interesting read.

How does this compare, speed-wise, to the UTF-8 validation done in simdjson?

Agree that static blogging is nice, but I think this specific look needs some tweaking - for example, there's too low contrast in color between the links and the background at https://inoads.com/blog

The % of programmers that actually need to know any of these numbers is tiny. I've done plenty of optimizations for performance-critical systems and have never known any of these numbers. Certainly, I know general principles like &qu

In that case, if header-only is outside the scope of the license, it begs the question why they would pick that license in the first place. But anyways, it doesn't seem clear from the passage how headers fit in, considering that these
