Qlik Sense Performance: From Slow to Fast with Hanumant Raut | BI Career & Qlik Mentor

Every Qlik developer eventually gets the same message: "The dashboard is slow." Often it comes on a Monday morning, from someone senior, right before an important review.

This book is your plan for that moment.

Qlik Sense Performance: From Slow to Fast Dashboards is a 70-page practitioner's playbook of real-world fixes for data models, load scripts, expressions and sheets. It includes ready-to-run test packs for Qlik Sense On-Prem (Enterprise on Windows) and Qlik Cloud.

The one rule it follows throughout: record a baseline, fix the biggest cause first, and measure again. One change at a time.

What's inside:

1. Why Qlik gets slow: how the engine stores data, the four places time goes (reload, open, calculate, render), and why cardinality is enemy number one
2. Measure before you fix: the five baseline numbers, a 15-minute baseline routine and a cardinality report script
3. Data model fixes (the biggest wins): synthetic keys, splitting timestamps, AutoNumber keys, dropping unused fields, and concatenated facts vs link tables
4. Load script and reload fixes: optimized QVD loads, incremental loads with insert, update and delete, ApplyMap instead of Join, and a layered QVD architecture
5. Expression fixes: replacing Sum(If()), set analysis on flags, Aggr() without the pain, Count(Distinct) alternatives, and calculated dimensions and variables
6. Sheet and front-end fixes: fewer objects, calculation conditions, taming big tables and pivots, and containers
7. Scaling up: Section Access that stays fast, summary and detail apps, ODAG, Dynamic Views and Direct Query
8. Server, cloud and migration: RAM and CPU on Windows, Qlik Cloud limits, and a 10-point check before you migrate

Test packs, not promises: 7 self-contained scripts generate their own sample data, so you can build the slow and fast versions side by side and see the numbers yourself. No files, databases or client data needed.

Five turnaround scenarios from Healthcare and Banking take you from the first complaint to the fix, in the order that works.

The Performance Toolkit includes:

1. A troubleshooting flowchart for the first five minutes
2. A release checklist to run before every release
3. A slow → fast cheat sheet of 18 patterns
4. A fast master calendar template with flags
5. A glossary

Written for three readers: new Qlik developers can read it front to back, experienced developers can jump to their symptom, and leads and architects get scaling patterns, migration checks and a checklist to hand to the team.

Format: PDF, 70 pages.
