The best performance improvements come from understanding, not upgrading

Hi,

Most people try to fix performance problems by throwing more hardware, more credits, or more magic features at the system.

After 20 years tuning some of the largest Teradata and cloud data warehouses in Europe, I’ve learned something much simpler:

Understanding beats upgrading. Every. Single. Time.

That’s why I’ve been writing deeply practical content about performance tuning Teradata & Snowflake.

If you want real, battle-tested insights without the fluff, here’s where I publish everything:

You’ll find:

• Honest performance tuning ideas
• Practical Teradata → Snowflake guidance
• Simple explanations of complex optimizations

If you work with large analytical systems - or plan to migrate one - I think you’ll find it genuinely useful.

Let me know what you want me to write about next.

Best regards,

Roland Wenzlofsky
