Katalon Studio is taking a lot of memory in task manager

When I start Katalon Studio (5.7.1) it takes about 500-700Mb, but after recording a short/simple testcase it increases to over 1 Gigabyte of RAM (only Katalon.exe!).
Is this normal?
My system meets the system requirements: i5, 3,5ghz, 4Gb RAM, 64-bits Windows 7.
Are there attempts to slim the Studio down regarding to memory usage?

Sounds reasonable to me.

Mine is using 1.8GB editing seven files some of them large lib/class files. Running one test under development.

Win7x64, i7, 16GB ram.

After upgrading to 5.10.1, I’ve noticed increased memory usage. Mine is up to 2.7 GB on a small project: 1 Test Case with 18 steps, 10 custom keywords, 14 Web Service Request objects, 3 profiles with 7 variables each. Win10x64, 16GM ram.

Add these lines to your katalon config file. They cut the memory usage down significantly.



That definitely helped

To which file should i add these properties. Is it the configuration file in katalon installation folder

Should be that one, yes.

We will have some memory tuning in upcoming releases.

To whom it may concern,

Katalon Studio version 7.0.0 is enhanced to reduce memory consumption by adding some JVM options.

Please first check out the release note and click here to download if you want to try out version 7.0.0 (beta).
