Answer
Troubleshooting steps:
- Identify high-CPU queries in DMVs
- Check plans for sorts, hashes, conversions
- Validate statistics
- Review index usage
- Investigate parallelism waits
- Check server MAXDOP settings
Quick Answer
For CPU issues: check sys.dm_exec_query_stats for queries with high total_worker_time. Look for missing indexes, non-SARGable predicates, or excessive recompilation. Execution plans showing large sorts, hash joins, or scans on big tables are CPU-heavy. Fixing those reduces CPU — indexes shift work from CPU to I/O.
