Hi! I have a beginner’s question… What has to be done on order that the tests run faster? they run very, very slow (I believe I have a wrong setting). Thanks in advance ---

Hi Mariana, Would you please provide details information on what you are trying to test and your system environment? Sometimes the system requirement is NOT met. Please refer to this [documentation](http://docs.katalon.com/display/KD/System+Requirements "documentation"). Liam ---

Hello, I am encountering the same issue. I did not change the settings but I think that it is the local settings of IE that are in cause. Indeed, several months ago it was working perfectly. Today I am reusing it and it is too slow. I tried an old version of Katalon - 4.7.2 and it is now slow as well. So I suppose it is not due to Katalon. Are you aware of any IE11 settings that could make the execution that slow. Ex: it takes around 5 seconds between each operations and the setting you’ve asked is set at 0 second. Thank you for your help ! ---

Im using the latest version Katalon Studio v5.3.0.1 win64 under IE11 \ win10 pro environment. I am encountering the same issue. It takes around 5 seconds between each key in while tesing the login page. I find IEDriverServer.exe in the folder configuration\resources\drivers\iedriver\_win64 is win32 version. And I tried to replace it with win64 version. And KS throw an error while testing. Obviously, Katalon cannot support win64v of IEDriverServer.exe. Is there any idea to solve this problem? thx~ ---

Hi, I have exactly the same issue. Windows 7, 64bit, Katalon Studio Version 5.3.1 Build 1. Neither Google Chrome, Internet Explorer, nor Firefox are working correct. Only the headless mode is working fine. For testing I just created a new project and used the “Sample Web UI Testing Project”. I clicked on “Run”, selected Chrome. Everything starts quick, right until Chrome starts and the step “Navigating browser to: ‘[http://demoaut.katalon.com](http://demoaut.katalon.com)’” pops up. Have a look at the execution trace below. 56s per test? There is sth. fishy. Please help! ![](https://s3.amazonaws.com/katalon-forum/editor/kl/xauekrnmd76p.png "Image: https://s3.amazonaws.com/katalon-forum/editor/kl/xauekrnmd76p.png") [sample.png](https://s3.amazonaws.com/katalon-forum/editor/kl/xauekrnmd76p.png) ---

Normally, the web testers encounter such types of circumstances. would you like to suggest some precautions or guidelines for improving test execution speed? ---

Hi, I am facing this issue too. Each action performed took at least 30 sec to execute. But I set it to 0 for action delay. ![Untitled](https://europe1.discourse-cdn.com/katalon/original/2X/e/eb01f7d45611113e53060ebe41fb6b79ec72a471.png) ![image](https://europe1.discourse-cdn.com/katalon/original/2X/5/56dda085fff80d10a9df391057442c80ec54a25d.png) I had tried Window -\> Preferences -\> Katalon -\> Proxy -\> Proxy Option: Use system proxy configuration. It was not like that, the execution used to be with no delays. Is it due to IE settings? Thanks and have a nice day. ---

Just for your interest. The “Smart wait”, newly introduced feature at KS 7.0, may slows down test executions.

you have to change the IE driver to **IE driver version x32** it will work. IE Driver Location: `\configuration\resources\drivers\` you can download it from here depending on your selenium version: [https://selenium-release.storage.googleapis.com/index.html](https://selenium-release.storage.googleapis.com/index.html) [Next page](https://forum.katalon.com/t/test-execution-is-very-slow/8370.md?page=2)
