[$] Approaches to reducing TLB pressure
The CPU’s translation lookaside buffer (TLB) caches the results of
virtual-address translations, significantly speeding memory accesses. TLB
misses are expensive, so a lot of thought goes into using the TLB as
efficiently as possible. Reducing pressure on the TLB was the topic of Rik
van Riel’s memory-management-track session at the 2025 Linux Storage,
Filesystem, Memory-Management, and BPF Summit. Some approaches were
considered, but the session was short on firm conclusions. ⌘ Read more
