I had a look at the video, but I don't think there is backpresure in this benchmark since there is only 512 connections max and each connections wait for the server response before sending a new request. So in other words the load gene

For Rust vs c++: - I never used rust but I like the language and the safety it provides. - a mainstream package/dependency manager is missing in C++ so rust is clearly better on this point. This is a big problem for the C++ commu

Me, the benchmark data is pretty slow to process.

I added -pipeline but I guess -with-batch is more explicit. I'll change it then. But anyway the techempower team will eventually add a special tag for batching. There is actually a version of lithium not using batching, check for &#x27

Some framework are using raw sql requests to skip the overhead of the ORM but they are still slower (lithium's ORM has no cost at runtime anyway). Coding everything in ASM would be insane and increadibly hard to ensure that this is the

The benchmark is clearly not perfect. But it is great for the community: It pushes all the framework maintainers to optimize their code, so kind of all users of all frameworks are indirectly positively impacted.

Indeed, sql query batching is the key (and I personally think that the techempower website should make it explicit), async communication with the db and the http client is also the key. FYI lithium is not using a libpq fork from 2016, it ha

The benchmark show that the frameworks has a big impact on performance. While all the frameworks are using the same database server, performances varies from 1x to 100x. While the benchmark focus on more req/s, we can also see it the o

It is linux only because it's based on epoll. It could be easily ported to macos and windows but my focus was to get the performances right first.

Can you do an AMA? of course! Why did you create lithium? To see how much C++ can get closer to dynamic langagues typically used for web programming and at the same time make absolutely no compromise on performances. How long have you been

by matt42 6y ago
Lithium development started 8 months ago and is not yet backed by a company. So it has clearly not a lot of traction yet. Just give it some time.

Removed the comparison with ASIO. But note that this is not "heavily in progress" but ready for production too. I took your remark for the closing callback. read now returns 0 and write returns false when the connection is closed

I did not spend too much time writing the documentation because of the simplicity of the library. I thought that the tcp echo example would be enough. But I'll spend more time in the Readme, at least fixing the language issues :)

Got it. I'll fix them asap thanks
