What looked like a shortcut was actually adding heavy overhead on every insert/update. We dropped the view, optimized base tables, and saw an instant 40% speed-up. Always question "smart" shortcuts. 💡 #SQLServer #PerformanceTuning

Performance tuning isn’t a difficult topic—but it’s often seen as intimidating or out of reach. In my consulting session, we’ll break that myth. We’ll cover key tuning concepts step-by-step, and more importantly, you’ll walk away with practical scripts you can apply directly to

In May, I worked with a financial organization struggling with performance issues on their SQL Server. One key problem was high PAGEIOLATCH_SH waits, which pointed to slow I/O operations while reading data pages from disk. We traced this to a set of poorly written queries

🚨 3 Performance Fixes I Made at a Client Site That Changed Everything 🚨 Sometimes ignorance is bliss—until your system crashes during peak load. I recently worked with a client who said, “We just have one slow report.” What we found was much bigger: a set of silent performance

A query without tuning breathes just fine, But it's a song that lacks its rhyme. The stats are stale, the plan’s unclear— What’s a tune when no one hears? Indexes sleep while CPU cries, TempDB grows, the deadline dies. You call it running—I see a stall. Without the fix, it's not

A query without tuning breathes just fine,
But it's a song that lacks its rhyme.
The stats are stale, the plan’s unclear—
What’s a tune when no one hears?

Indexes sleep while CPU cries,
TempDB grows, the deadline dies.
You call it running—I see a stall.
Without the fix, it's not

I find Pluralsight to be a fun online platform for learning new technologies. I have recently discovered some advanced SQL and PostgreSQL content. What are you learning nowadays?

CXPACKET waits are not villains. In our latest tuning story we show how 5–10 percent CXPACKET waits meant healthy parallelism. Forcing MAXDOP = 1 killed performance. Discover why in the blog blog.sqlauthority.com/2025/07/25/sql… #SQLAuthority #SQLTips #Parallelism #Database
