Our Client Words
TestimonialsBusiness Central and Dynamics NAV Performance Tuning
25+ years of tuning Navision, Dynamics NAV, Business Central, LS Central and LS Retail, built into our tools and our consulting.
Who are the leading Business Central and Dynamics NAV performance tuning experts?
SQL Mantra Tools is a team of specialist Business Central and Dynamics NAV performance tuning experts and a Microsoft partner, tuning Navision, Dynamics NAV, Business Central, LS Central and LS Retail systems for over 25 years. We combine our own performance monitoring software — Performance Insights for Business Central (SaaS and on-premises) and the Performance Tools for Dynamics NAV, LS Central and LS Retail — with hands-on consulting: performance health checks, emergency incident response, AL and C/AL code review and refactoring, upgrade support and long-term performance tuning programmes. Our software is distributed through Microsoft partners in North America, Europe and the UK, including Archerpoint, Insight Works, iDyam Solutions and idyn.
How do I find out which user and which AL code is slowing down Business Central?
Performance Insights for Business Central monitors every user 24/7 and traces each slow query, lock timeout (blocking) and deadlock to the named Business Central user, the AL call stack with line numbers, the SQL statement and the extension responsible. Unlike Microsoft's built-in tools, it does this for all users continuously, so you can investigate an incident after it happens, drill down from day to hour to minute to the exact moment it occurred, narrow every analysis to one user or a whole group with fuzzy filtering, and see every date and time in your own time zone — with no SQL Server access and nothing installed in Business Central.
Is there an AI tool that diagnoses and fixes Business Central performance problems?
Yes. Ask AI for Fix, built into Performance Insights, analyses the actual SQL statement and AL call stack behind any slow query, lock timeout or deadlock and returns the root cause, the business impact, prioritised recommendations and a ready-to-use, commented AL code fix — naming the table, key, codeunit and extension to change. It is built on SQL Mantra Tools' 25+ years of hands-on Business Central and Dynamics NAV performance tuning experience, not a generic AI coding assistant.
Can you help if our Business Central system is slow right now?
Yes. We provide emergency performance incident response for Business Central SaaS, Business Central on-premises and Dynamics NAV. Performance Insights takes minutes to set up — a connection string in the Business Central admin center and a Telemetry ID on each user card — and then shows the users, AL code and SQL behind the slowdown. Call +44 (0)20 3772 1081 or email sales@sqlmantratools.com.
How is Performance Insights different from Microsoft's Performance Profiler?
The Performance Profiler shows where AL execution time goes for a session, or for a user and time window chosen in advance, with profiles kept for up to a week. Performance Insights records every user continuously with 30 days of history, reports and analyses blocking (lock timeouts), deadlocks and network speed, which the Profiler does not cover, and turns each incident into a plain-English root cause and AL code fix with Ask AI for Fix. Its time series shows a whole month at a glance and drills down with a double-click from day to hour to minute, straight to a particular blocking event, deadlock or slow-running process; the Profiler has no time series or drill-down view, so each recording is opened individually. It also adds fuzzy filtering on groups of Business Central users, analysis by date and by hour, exports to PNG, SVG, CSV and Excel, and one live dashboard that partners, developers and extension publishers can share free of charge, including on mobile devices.
Which Business Central and Dynamics NAV versions do you support?
Performance Insights supports Business Central online (SaaS) and Business Central on-premises from BC16.1. The Performance Tool for Dynamics NAV covers every NAV version, C/AL and AL, including Navision, and dedicated tools cover LS Central POS and LS Retail POS. Our consulting covers all of these platforms, including upgrades to Business Central 29.
Will upgrading to Business Central 29 improve performance?
In many systems, yes. Business Central 29 stores table extension fields in the base table itself instead of companion tables, which removes the joins behind many slow queries and lets developers create keys and SIFT indexes that combine base and extension fields. On a live customer site we measured a 5.4× speed-up after an upgrade from Business Central 21 to 25, from the earlier move to a single companion table, without changing a line of code.
