Which is exactly what Mellanox and others are doing. At QuasarDB, we’re using their drivers to bypass the kernel entirely, which (at scale) saves tremendous amounts of CPU load.
- sanjayts 7y agoAre you talking about these[1]? Also, would you have a rough ballpark figure on the CPU load reduction you have seen using these? [1] http://www.mellanox.com/page/products_dyn?product_family=209&mtag=pmd_for_dpdk http://www.mellanox.com/page/products_dyn?product_family=209...
- stingraycharles 7y agoActually it’s VMA: http://www.mellanox.com/page/software_vma?mtag=vma http://www.mellanox.com/page/software_vma?mtag=vma 100GBit would usually put enormous strains on the CPU (to the point it’s pretty much only doing that), which is taken away entirely by using this. As it turns out, hardware appears to be much faster at these types of things than general purpose CPUs. :)
