June 2025 performance summary for facebook/fboss focusing on stabilizing memory headroom calculations for buffer pools across ASIC types. Reverted changes to unify the headroom sizing, ensuring consistent usage of memory buffer counts rather than per-core counts. This change reduces cross-ASIC variance, lowers risk of over- or under-provisioning, and improves memory resource predictability across platforms. No new user-facing features were delivered this month; the work strengthens reliability and maintainability of the buffer pool subsystem.
