Hi Suresh,
Thanks for contacting Syncfusion support.
Maybe scripts and CSS files size cause this problem. The following two ways to reduce the time while same page gets reloaded,
Compress the ZIP file using GZIP
We suggest you to use GZip. If you use the GZip for compressing the file size, you will have optimal solution in the production server. Please refer to the documentation for information on GZip.
Referring Grid dependent files alone:
We can also refer individual files for rendering the Grid control instead of referring the ej.web.all.min.js file. Please refer to the below documentation, where we have listed out the dependent files for rendering the Grid control. Because its reduce the file size and also reducing the load time while page gets again build. Please refer to the Help documentation for more information,
We can find the above mentioned files from the below mentioned installed location.
Script Location:
C:\Program Files (x86)\Syncfusion\EssentialStudio\XX.X.X.XX\JavaScript\assets\scripts\web
Here, XX.X.X.XX denotes the Product Version such for example, 15.2.0.46
Also, we suggest you to use the CSG scripts.
custom script generator is used to generate scripts and themes for only dependent Control .
This is generate the grid and dependent controls script and css only.
Refer the following UG Link for your reference.
Please let us know if you need further assistance on this.

Venkatesh Ayothiraman.
