When I launch Katalon, the project is very slow to open. It takes over 15 minutes or more for my project to open. The project is not very big. I have about 50 test cases, maybe around 14 test suites.
Hi @mgrandillo, it has been slow since about version 7.0, 7.1. Some others have mentioned as well. My startup time is about 40-60 seconds when it was about 15-20. I have a larger project but it is still slow(er) to start.
I wish there was a load metric provided by Katalon to measure performance times from release to release. They have automated API performance metrics so maybe they are looking into measuring the project load times.
Please take a screenshot while your project is being opened and stacked.
The screenshot may indicate to us what is taking long time to proceed.
try to disable testops integration in your project if you are not using it.
Tried that, it didnt work.
FYI, it took about 12 minutes to open the project.And when it finally opened, it shows at the bottom “loading plugins”…(100%). Stays in this state for a few minutes. So in total i would say you need to wait at least 15 minutes to have access to Katalon once the project is loaded.
Please share the
.log file that Katalon Studio wrote while you experienced slow initialization.
- Windows logs folder:
<Katalon Studio folder>\config\.metadata\.log
- macOS logs folder:
To make the
.log file concise, please follow the steps
- stop Katalon Studiio
- delete the
- restart Katalon Studio and open the project … you need to wait for 15 minutes?
- stop KS again
- share the file to us.
I attached my .log file here just for your reference — I experience no slowness at all. Do you find any remarkable difference in your .log file? — eg. Java Stacktraces printed repeatedly, etc.

Could you share the
<projectDir>/.classpath file of your problem project?

.classpath file I found
<classpathentry kind="lib" path="C:/Users/mgrandillo/Downloads/Katalon_Studio_Windows_64-7.7.2/Katalon_Studio_Windows_64-7.7.2/plugins/com.kms.katalon.core_126.96.36.199101290615.jar" sourcepath="C:/Users/mgrandillo/Downloads/Katalon_Studio_Windows_64-7.7.2/Katalon_Studio_Windows_64-7.7.2/configuration/resources/source/com.kms.katalon.core/com.kms.katalon.core-sources.jar">
This line indicates that this .classpath file was created by Katalon Studio 7.7.2. On the other hand @mgrandillo is using Katalon Studio ver 7.9.1 now. The versions are mismatching. I guess that this discrepancy is the reason why he experiences the slow startup of KS project.
I experimented on my PC. I downloaded the .classpath file which @mgradillo provieded, overwrite it into one of my Katalon Project X. I started KS on my PC and opened my Project X, and watched how the
<projectX>/.classpath file. Of course it was the same as the @mgradillo’s one, but after some seconds passed the file was overwritten by Katalon Studio. The Project X launched successfully. I checked the .classpath file and found it was new — compliant to KS v7.9.1.
This experiment tells me that the
.classpath file will be silently/automatically overwritten by Katalon Studio at project startup. Therefore it is safe to delete the
.classpath file, as it will be restored anyway.
However, as noted, @mgrandillo is using KS 7.9.1 while in his project he has a .classpath file for KS7.7.2. I don’t see the reason why this could happen. Why his KS 7.9.1 does not overwrite the .classpath file in his project? Katalon Studio seems to have some fault here, is not robust enough.
Similar issue is here
Anyway, I would recommend you to try
- take a full backup of your project just in case of mistakes
- stop Katalon Studio
<yourProject>/.classpathfile — to avoid the version discrepancy found above
<yourProject>/bindirectory as well — to make the project clean
- restart Katalon Studio, open the project
Do you use Git for your project? If yes, do you save
.classpath file in the Git repository? I think you should NOT save the
.classpath file. Just .gitignore it.
The following is the .gitignore file generated by KS 7.9.1:
.gradle bin Reports Libs output !output/.gitkeep build .classpath .project
The Libs folder should be also removed. This will force Katalon to properly re-index the entire project.
In fact all files mentioned by gitignore can be safely removed.
