Here is a summary of the key findings and recommendations from the SQL Server Health Check Review:
### **Agenda**
- Server Overview
- Top Wait Stats
- Notable Items
- Immediate Recommendations
- Additional Recommendations
---
### **Major Performance Recommendations**
1. **Index Optimization**
- Identified 96 near-duplicate indexes across multiple databases.
- Recommended:
- Dropping 35 indexes.
- Altering 12 indexes to cover queries previously handled by the 23 being dropped.
- Keeping 49 indexes.
2. **Compression Implementation**
- Recommended page-level compression on all tables and databases.
- Estimated 40% space savings, improving I/O performance.
3. **SQL Agent Job Failures**
- Several jobs fail due to:
- Conversion errors.
- Null values affecting aggregate operations.
- Deadlock victims.
- Suggested fixing these common issues.
4. **Deadlocks**
- **ReportServer:** 120 deadlocks per day due to AD user ownership issues.
- Recommendation: Replace trigger with a weekly job.
- **Mobilei Database:** SELECT vs. UPDATE deadlocks impacting performance.
- Recommendation: Add an index to prevent bookmark lookups.
5. **Log Shrinking Jobs**
- Frequent log shrinking causes fragmentation.
- Recommendation: Adjust auto-growth settings and remove scheduled shrink jobs.
6. **Unused and Missing Indexes**
- Recommended dropping unused indexes to reduce overhead.
- Suggested adding missing indexes to improve query performance.
7. **Stored Procedure Refactoring**
- Identified common issues such as:
- Implicit conversions.
- Non-SARGable WHERE clauses.
- Suboptimal query patterns.
- Recommended refactoring procedures.
8. **High Blocking on EcmData.EcmEvent Table**
- Recommended adding indexes to reduce exclusive table locks.
9. **Backup Optimization**
- Suggested using backup striping for faster backup and restore processes.
10. **Buffer Pool Extensions**
- Recommended configuring buffer pool extensions to reduce I/O pressure.
11. **vCPU Configuration Issues**
- SQL Server is running on 16 sockets with 1 core each.
- Recommendation: Change to 2 sockets with 8 cores per socket for better NUMA optimization.
---
### **Immediate Recommendations**
1. **Parallelism Settings**
- Set MAXDOP to 8 and Cost Threshold for Parallelism to 40.
2. **Storage Optimization**
- Migrate data/log files to 64K block size drives.
3. **Table Compression**
- Implement row/page compression to optimize storage and performance.
---
### **Additional Recommendations**
- Index Consolidation and Cleanup:
- Remove unused indexes.
- Consolidate redundant indexes.
- Add high-value missing indexes.
- Backup Optimization:
- Use multi-file striping for faster backups.
- Statistics Management:
- Update outdated statistics more frequently outside of index maintenance jobs.
---
### **Notable Items**
- High CPU usage (60%) with suboptimal parallelism settings.
- 140 deadlocks per day, mainly related to the Report Server.
- Disk I/O issues with significant latency on drives D and E.
- 64,513 cached query plans for a single query, indicating parameterization issues.
- SQL Server Agent job failures due to common errors.
---
### **Minor Performance Recommendations**
- Implement differential backups to reduce I/O.
- Partition large tables to improve query performance.
- Cleanup of old linked servers.
- Enforce stronger password policies for SQL logins.
- Address untrusted constraints in several databases.
- Implement Transparent Data Encryption (TDE).
- Review and adjust Virtual Log Files (VLFs) and auto-growth settings.
- Optimize SSRS subscription workflows to remove stale records.
