Characterization of the Impact of Hardware Islands on OLTP [PDF]
The VLDB Journal, 2015 Modern hardware is abundantly parallel and increasingly heterogeneous. The numerous processing cores have non-uniform access latencies to the main memory and processor caches, which causes variability in the communication costs. Unfortunately, database systems mostly assume that all processing cores are the same and that microarchitecture differences ...

Improving instruction cache performance in OLTP [PDF]
ACM Transactions on Database Systems, 2006 Instruction-cache misses account for up to 40% of execution time in online transaction processing (OLTP) database workloads. In contrast to data cache misses, instruction misses cannot be overlapped with out-of-order execution. Chip design limitations do not allow increases in the size or associativity of instruction caches that would help

An In‐Depth Characterization of Page Fault Handling in Modern Persistent Memory Systems
Concurrency and Computation: Practice and Experience, Volume 38, Issue 7, April 2026.ABSTRACT Recent advancements in Persistent Memory (PM) technologies have enabled the integration of such devices directly into the processor's memory hierarchy, allowing them to be accessed via standard load/store instructions. These developments have revived interest in the design and implementation of systems capable of effectively supporting PM.
