Description
Commercial Production Objective
Eradicate hardware translation lookaside buffer (TLB) cache miss bottlenecks under extreme data-plane traffic surges, dropping memory access jitter parameters to zero .
Bare-Metal Technical Specifications
- Static HugePages Reservation: During boot initialization runtime loops, programmatically bypass standard OS memory paging allocations by locking physical 2MB HugePages blocks.
- Direct Pointer Ring Alignment: Within
internal/storage/buffer_pool.go, direct-map the pre-allocated fixed-size unsafe pointer circular arrays into this isolated hardware memory matrix . - Zero CPU Bus Drag: Prevents OS kernel virtual memory page fault loops entirely, ensuring microsecond tail latency clamping under maximum tenant saturation loads .

Research direction
Start by reading internal/storage/buffer_pool.go and identify how its fixed-size unsafe pointer circular arrays are allocated and used. Then trace the boot initialization runtime loops referenced by the issue and research Linux 2MB HugePages reservation and static mapping. Done means the buffer pool uses the requested HugePages mapping without standard paging, with evidence that the stated latency and page-fault goals are met.
