> Why do you need single core performance so badly Because on the cloud, performance is directly correlated to your monthly bills.

Why not, it's the customer that ends up paying because there's less performance per machine, and so they may need more of them. If all cloud providers use this fix then there's really nothing you can do. Some may provide true

That depends on the allocator used. The default libc one works but isn't great performance-wise. It is possible to intercept calls to malloc/free by using LD_PRELOAD on Linux. That will allow you to use allocators such as jemalloc

If you give gcc the appropriate 'march' parameter it can use vectorisation automatically if it figures out it can do it. The main argument here is that native languages let you get the most out of your CPU if you want, whereas wit

I'd define modern as using RAII extensively and using C++11 at least. As for algorithms, I honestly don't know what you mean. They're all documented online with respective big-O running times[1]. If you're talking about

There is an open-source project by LMAX (a forex trading company) called Disruptor[1] that squeezes as much as possible out of the JVM. It's awesome. I ported it to C++ years ago when I wanted to learn about low-latency techniques. How

Not really. Only shared_ptr uses ref counting, unique_ptr doesn't, and looking at our code base (highly networking orientated) we only use shared_ptr once. You could, in theory, use shared_ptr everywhere, but then you're not using

Drivel. You can't have it both ways. It's easy to see what you're doing in C++ because you have to do it! It's the whole point of the language, and apparently the source of bugs. Correct me if I'm wrong, but I doubt

Look at the networking sourc code for Redis. It meets all your requirements and isn't that big.

Sorry, this is hand wavy nonsense. One counter example, we switched from Cassandra (JVM) to Scylla (C++). It was a win in terms of both query latency and infrastructure costs as we required fewer machines to handle the same load. As for hav

We use sqlite as a smaller cache of a much larger postgres db. The cache is generated by a job and yes is regenerated every time before being pushed to machines that need it.

I am the opposite. I develop on Linux via VMWare Player running on a Windows host. I don't want Linux as the main OS on my personal desktop and I can keep work related stuff on its own VM. I've never noticed any non-bare metal spe

We use ZeroMQ a bit. It's been pretty much flawless as far as I can see but I get the impression that it's becoming obsolete. Is RabbitMQ a viable replacement?

I think it was welcomed with open arms by less experienced devs because it made code easier to compile, and rightly so. C++'s compiler messages are off-putting. For others, it was worrisome because it made code easier to compile, and r
