Looking for programmer volunteers who want to contribute/learn about low level C++, Linux, Networking, high frequency trading.
Amazon (AWS) cloud EC2 instance specific role (Kernel and User space networking, linux OS related). Amazon has it's own network card with it's own linux driver (open source), for user space they use DPDK (open source). https://github.com/amzn/amzn-drivers I've measured the time between calling tcp send in software, and packet leaving the NIC (network card), it is around ~50 microseconds latency, aws also stated in a paper it is around that number. Goals:- Figure out the way to build from source code and load the kernel.- Reduce latency

Dragonflydb – A modern replacement for Redis and Memcached
Of course, there are.
I was mostly running on AWS. In terms of hardware, for small packets loadtests most systems are constrained on throughput, i.e. number of packets per second. Some systems saturate on interrupts reaching 100% CPU on all cores and some can not even saturate the CPU and you will see that CPU is at 60% but you can not go beyond some limit. Best systems networkwise are c6gn family types. They are also better than other cloud provide. btw, you mentioned hypervisors... About 8 months ago I opened a bug on AWS Graviton team https://github.com/amzn/amzn-drivers/issues/195 - about performance issue they had on their instances at high throughput. Recently they issued the fix. I suspect it was in their hypervisor.
In terms of my software I found many performance bugs at those speeds. For example, using a default allocator is a big no. I use mimalloc for uncontended allocations. In general, you can not use mutexes and spinlocks at those speeds. Those will just cripple the system. Sometimes it can be very annoying since you can not rely on a 3rd party library without carefully analyzing its design. For example, I could not use openmetrics c++ library because it was not performant enough. Even to implement a simple counter, say to gather statistics for INFO command becomes an interesting engineering problem:

Ask HN: Anybody enabled IOMMU on AWS metal servers?
https://doc.dpdk.org/guides/nics/ena.html
and:
https://github.com/amzn/amzn-drivers/tree/master/userspace/dpdk/enav2-vfio-patch
Enabling IOMMU on i3 or c5 metal instances is as easy as adding "iommu=1 intel_iommu=on" to /etc/default/grub followed by update-grub, reboot.
I can't get this to work. Everything I update grub and reboot I cannot re-connected via ssh. Also EC2 console fails to get good status.
My config:
Ubuntu 20.04 stock AWS AMI x86 64-bit
