Katalon runs so slow

[giaun1981]

Hello,
I used Katalon free version to learn and search by myself. It took 10 minutes to run 16 test cases but from last month it took 1 hour to run them without my change. Any idea to fix it?

Thanks,
Giau Nguyen

What version(s) of Katalon?

[giaun1981]

Version: 7.7.2
Build: 205

We need to identify which statement(s) in your test case script takes long time. That would be the first thing we need to know.

@giaun1981
Please look the Log Viewer while your test is running. Possibly you will notice your test sometimes blocks waiting for something for minutes. What do you find?

---

Also please show the .log file created by Katalon Studio. The file location is as follows:

• Windows logs folder: <Katalon Studio folder>\config\.metadata\.log

• macOS logs folder: file:///Applications/Katalon%20Studio.app/Contents/MacOS/config/.metadata/.plugins/org.eclipse.ui.workbench/log

we may find something informatinve in the .log file.

Chrome and other browsers are usually automatically upgraded silently while you are not aware of. This often causes confusions/problems. You should try updating WebDriver modules and try again. See
https://docs.katalon.com/katalon-studio/docs/handle-webdrivers.html

After updating to Katalon 7.8 and then update ChromeDriver, the all test cases are failed because they are run very quick and it’s not enough time to run step by step. I don’t know. Do you have any idea with new version?

I had a look into the .log file you provided, but I could not find informative things.

You have upgraded your KS? Then many things can change. Nobody knows what happens to you. You need to restart your research from scratch.

Your test runs no longer slow? Then the title of this thread “Katalon runs so slow” is not describing you problem appropriately. You should close this thread, and create new one with better title.

If you want us help you finding the reason why your test failed, please show the Console messages when your test failed.

It’s dangerous to upgrade to new version. All test cases are failed. I did down grade to version 7.7.2 and all test cases are passed but it is back to slow issue. slow is better than failed. Idea?

@giaun1981 I think you should read this carefully and respond with everything that you think might help us understand your problem. In your case, make sure you include references and screenshots to your delay/smart wait settings.

My test is BROKEN! NOTHING WORKS! HELP ME! Relax. We get it. We really do. There are some pretty smart and clever people on this forum, but you must realize, they are not magicians or wizards or gods.

Having KS 7.7.2, still you should do “upgrade WebDriver modules” before running test cases.

[giaun1981]

Can you let me know what info you really need to understand my issue?

@giaun1981

I think you should share the report folder for the last month and recently run.

Sorry I am using free version so there is no report

Hi,

We have a significant update on this in v8.2.0 recently, now:

• Improved loading time in Katalon Runtime Engine. Results from our benchmarking tests show: 2x faster for big projects, 1.5x faster for small and medium projects.
• Improved responsiveness and loading time for big projects in Katalon Studio. Results from our benchmarking tests show: renaming/opening test cases 2x faster, moving test cases 1.5x faster.
• Reduced 12% memory consumption on average of Katalon Studio when opening/executing tests.
• Reduced 30% memory consumption on average of Katalon Runtime Engine for long execution sessions.

You can find out more in the release note here https://docs.katalon.com/katalon-studio/new/version-8x.html#enhancements

Hi @chrisstu,

I still have the same slowness issue with KS 8.2 version. It takes close to 15mins for my project to load. And also again to switch from Test case to Keywords it takes 10-15mins. Tried doing as below but still no luck.

• Log out of Katalon.
• Took backup of <MyProject>
• delete <MyProject>\.classpath file
• delete <MyProject>\bin
• delete <MyProject>\lib
• Restart Katalon and tried opening my project, still noticing same slowness.

Any help here is highly appreciated.
Thanks in Advance!!

Please have a look at the following post. You may find something advising.

Katalon Studio 8.0.0 much slower in opening and saving files

I have currently applied Katalon Studio in my project I cannot continue my job and have to work on something else while awaiting your response Operating System Windows 10 Katalon Studio Version 8.0.0 Katalon Studio logs .log.zip (4.1 KB) Event Log is full of the following messages and every open of a file to edit or a save takes 4 or 5 secs and generates more of these messages. This never happened prior to release 8.0.0 CodeSelectRequestor: Could not proceed due to null declaring type …

This post was reported for v8.0.0, and we regard the problem has already been resolved in v8.2.0.

@duyluong

However, @Aruna now reports v8.2.0 is still slow. This may indicate there could still remains a problem in v8.2.0

• Does this happen on new project?
