Initial Benchmarks Of The Performance Impact Resulting From Linux's x86 Security Changes

Tuesday 2nd of January 2018 11:35:26 PM
Over the past day you've likely heard lots of hysteria about a yet-to-be-fully-disclosed vulnerability that appears to affect at least several generations of Intel CPUs and affects not only Linux but also Windows and macOS. The Intel CPU issue comes down to leaking information about the kernel memory to user-space, but the full scope isn't public yet until the bug's embargo, but it's expected to be a doozy in the data center / cloud deployments. Due to the amount of interest in this issue, here are benchmarks of a patched kernel showing the performance impact of the page table isolation patches.

My Linux story: Coding not required

For more than 15 years, I have earned a living working exclusively with open source products. How did I get here? In many ways, my journey started before Linux existed. In college, I had friends who were admins in the engineering computer lab. Although I did not do too well in my CS programming classes, as a hobby and to spend time with my friends I learned about newgroups, ftp sites, and Unix systems. As a data aide student intern, I realized I made a good translator between the astronomers and the C programmer computer support staff. I could read just enough code to identify the problem, but not enough to actually fix it. Read more
