Thank you @HansS
as what i read right now, i should have no problem at all.

So why my flows are very slow!
is there specific System Requ. needed for KNIME 5.2.5?

I am experiencing the same issues with the new version (5.2.5) of KNIME. Doesn’t throw any error/warning. The UI simply freezes, and my entire laptop stops responding. This problem did not occur with version 4.7.0. Since upgrading (last month), I have not been able to run my workflow to completion even once.

System Configuration:
Installed RAM: 8.00 GB (7.86 GB usable)
Processor: Intel(R) Core™ i5-7300U CPU @ 2.60GHz 2.71 GHz
System Type: 64-bit operating system, x64-based processor

@RamyHussein @Khushboo_Yadav how much RAM so you have assigned to knime?

How large is the data you are processing when zipped.

You might try to switch from Raw based compression to columnar based compression (in the settings) but maybe test it on a copy of your workflow.
