In this post I'll look at the Linux kernel page table isolation (KPTI) patches that workaround Meltdown: what overheads to expect, and ways to tune them. I then analyzed performance during the benchmark ([active benchmarking]), and used other benchmarks to confirm findings. Much of my testing was on Linux 4.14.11

And today, we still have type in a digital context, but it travels through cables, wirelessly on smartphones, and in virtual reality glasses in 3D. Once again, even more inconsistency is introduced because they would most definitely test their typefaces with different typographic designs and typesetting settings. Stay tuned!

For specific information on I/O tuning and balancing, you will find more details in the following document. The BPool consumes the majority of the user mode address space leaving only a few 100 MB of the virtual address range free for thread stacks, DLLs, and other activities.
