SQL Server I/O Bottleneck Assessment

I’m running SQL Server 2022 Enterprise in a production environment and my error log is filling with messages such as  FlushCache: cleaned up 1 153 918 bufs with 102 676 writes in 68 446 ms (avoided 71 188 new dirty bufs) for db 5:0 The frequency and volume of these entries suggest aggressive checkpoint activity, heavy write I/O and, quite possibly, a buffer-pool or storage-tier mis-configuration. Before I change memory allocations, checkpoint settings or tempdb/file layout, I want a seasoned SQL Server performance specialist to step in. What I need from you • A concise root-cause report explaining why the excessive FlushCache events occur • A wait-stats and I/O subsystem deep-dive, correlating waits, file stats and underlying storage performance • Configuration recommendations covering memory, MAXDOP, checkpoint behavior, trace flags (if relevant), file sizing and tiering strategies • A clear, ordered remediation plan that I can implement (or have you implement) with minimal production risk Acceptance criteria • Findings backed by DMVs, PerfMon counters or storage metrics captured during analysis • Actionable recommendations with estimated benefit and required change window • A follow-up Q&A session once I have reviewed your report If the engagement goes smoothly I’d like to discuss an ongoing advisory arrangement, but for now consider this a discrete project with a well-defined deliverable set.
