Is your ColdFusion app running too slowly? We find the cause, fix it, and prove the result with measurements.

Slow pages, random hangs, out-of-memory errors, or a server that only behaves after a restart? These are rarely random. They have a cause, and the cause can be measured. Contact us for a FREE consultation and tell us what you are seeing, or read the short version below first.

The short version: what a slow ColdFusion app audit covers

  • A slow ColdFusion application usually has one or two root causes, such as memory pressure, a handful of slow queries, or a caching gap. A measured audit finds them before anyone changes anything
  • We review the JVM and garbage collection, ColdFusion Administrator and Tomcat settings, database queries and indexes, caching, and application code, using real monitoring data from your own server
  • You receive a written findings report with prioritised fixes, and we can implement them for you
  • Applies to Adobe ColdFusion on any supported version, and to Lucee for the JVM, database and code layers
  • A performance audit typically takes 1 to 3 business days. A technical debt analysis of a full codebase (200 to 500 files) takes 5 to 8 business days. We confirm the timeline in a fixed-price quote after the discovery call

A ColdFusion application rarely gets slow for no reason, and it is rarely slow for the reason people first suspect. Teams often respond by adding RAM, restarting the server on a schedule, or blaming the last release. Sometimes that helps for a week. The problem returns because nobody measured what was actually going wrong.

Our approach is the opposite. We measure first, change second, and measure again. IT Landmark has worked on ColdFusion servers and applications for more than 25 years as an official Adobe ColdFusion Partner, across 600+ clients, so most of what we find on a slow server is something we have seen before.

Signs Your ColdFusion App Needs a Performance Audit

These are the symptoms we hear most often when a client first contacts us:

  • Pages that used to load quickly now take several seconds, especially at busy times of day
  • The server hangs or stops responding, and a restart fixes it for a while
  • CPU sits high with no obvious cause, or spikes when particular reports or searches run
  • Out-of-memory errors, or memory use that climbs steadily until something gives
  • Requests queue up or time out under load, even though traffic has not changed much
  • Scheduled tasks overrun and collide with user traffic
  • Costs keep rising because the answer so far has been a bigger server

If two or more of these sound familiar, an audit will almost certainly find something specific and fixable.

What Our ColdFusion Performance Audit Covers

A slow application can be caused at several layers, so we look at all of them rather than guessing which one matters.

JVM, memory and garbage collection

ColdFusion runs on the Java Virtual Machine, so heap size, garbage collection behaviour and metaspace settings have a direct effect on response times. We review the JVM configuration against your real memory profile and look at GC logs for long pauses. Memory leaks and oversized session or cache scopes show up here.

ColdFusion Administrator and Tomcat settings

Request thread limits, template and query caching, trusted cache, session settings, debugging output and connector configuration all affect throughput. We check each against how your application is actually used, because the right values depend on the number of CPUs, the load pattern and the application itself.

Database queries and indexing

In many slow applications, a small number of queries account for most of the delay. We identify the slowest and most frequently run queries, review execution plans and indexes, and look for patterns such as queries inside loops or queries that return far more data than the page uses.

Caching strategy

Caching the right things for the right length of time removes work that never needed repeating. We look at what is cached, what is not, and where stale data risk makes caching unsafe, so the recommendations fit your application and not a generic checklist.

Application code

We trace the slowest requests to the functions and templates responsible. Typical findings include unscoped variables, repeated object creation, inefficient loops, heavy work done on every request that could be done once, and blocking calls to external services.

Load testing

Where it is useful, we use Apache JMeter to reproduce load against a test environment, so we can show a before-and-after comparison instead of relying on opinion.

How We Find the Cause

We work from evidence collected from your own server. Depending on your environment, that includes:

  • Production monitoring with FusionReactor, SeeFusion or the Adobe ColdFusion Performance Monitoring Toolset, whichever you already run or are comfortable adding
  • Thread dumps taken while the application is slow, to see exactly what requests are waiting on
  • Heap analysis and GC log review for memory problems
  • Database slow-query logs and execution plans
  • Apache JMeter for load and regression testing

If you have no monitoring in place today, setting it up is usually the first step, because without it the next slowdown will be just as hard to diagnose.

What You Receive

  • A written findings report that explains what is slow, why, and how we know
  • A prioritised list of fixes, ranked by expected benefit against effort and risk
  • Clear separation between quick configuration wins and changes that need code or database work
  • An honest view on whether the real constraint is the application, the server, or the ColdFusion and Java version underneath it

When the Version You Are Running Is Part of the Problem

Sometimes the audit shows that tuning alone will only get you so far. Older ColdFusion versions may have reached the end of Adobe’s support lifecycle, and the Java runtimes they support may also be outdated or approaching the end of their supported life. That can create both security and maintainability risks.

Adobe ColdFusion 2025 is supported on JDK 21, while older ColdFusion releases have different Java and support requirements. Adobe’s current support lifecycle shows that ColdFusion 2018 reached the end of extended support in July 2024, and ColdFusion 2021 reaches the end of extended support in November 2026.

An upgrade is not automatically a performance fix, and we will not recommend one unless your measurements point to it. When an upgrade does make sense, we can plan it as a separate piece of work through our ColdFusion upgrade and migration service, so you can make the decision with full information.

Our Process

  1. Discovery: we learn the symptoms, the history and what has already been tried.
  2. Baseline: we measure current behaviour with monitoring, so improvements can be proven later.
  3. Analysis: we trace the symptoms to root causes across JVM, server, database and code.
  4. Report: you receive findings and a prioritised plan.
  5. Fixes: we implement agreed changes, or hand the plan to your own team.
  6. Re-test: we measure again and compare against the baseline.

Frequently Asked Questions

You usually cannot tell by looking, which is why we start with monitoring and thread dumps. If many different pages are slow at the same moment, the cause is often the JVM, memory or database. If one report or page is consistently slow, the cause is usually a query or a piece of code. An audit separates the two.

How long does a performance audit take?

A performance audit typically takes 1 to 3 business days. If you also want a technical debt analysis of a full codebase (200 to 500 files), allow 5 to 8 business days. We confirm the timeline in a fixed-price quote after the discovery call.

Do you need access to our production server?

Read access to monitoring data, logs and the database is usually enough to diagnose most problems. Changes are agreed with you first and made in a controlled way. We can also work from a staging copy where that is a better fit.

Will you rewrite our application?

No. The aim is to fix the specific causes of slowness in the application you have. If a larger change is ever justified, we will show you the evidence and let you decide.

Does this work for Lucee as well as Adobe ColdFusion?

Yes for the JVM, database, caching and code layers, since Lucee runs on the JVM and the same principles apply. Settings that are specific to the Adobe ColdFusion Administrator do not apply to Lucee.

Will upgrading ColdFusion make it faster?

Not automatically. A newer version and Java runtime can help, but an unindexed query or a memory leak in your own code will follow you to the new version. We measure first, so any upgrade decision rests on evidence.
