Slowness in server ui

Mdkhamru · September 2, 2021, 1:11pm

Hello Team

Thanks for keep doing a great job, I need a small suggestion on the server

We had hosted kobo on the high-end server and the surveys are working fine when we are running 500 users but after people keep on increase the Web KPI UI is loading slow and while clicking sharing survey it almost took 3 minutes to load

Kindly suggest server configuration for smooth usage or what is the server configuration Humanitarian Organizations are we using backend and front end in suppurate server

@Kal_Lam please assist here

@Mdkhamru, do you mean you are sharing your survey project with 500 users on a self hosted server?

Hi @Mdkhamru, unfortunately this is currently a performance issue with asset sharing and has been logged here (you will notice the same issues on our production servers):

Sharing form to many users is very slow

Back end

## Description Sharing a form if it's already shared with a large number of u…sers is very slow. It takes about a few minutes to complete the operation after it's shared with a few hundred users and during that period the UI is unresponsive. It happened on the installation of Kobo on a separate server (Ubuntu 18.04, 16GB RAM, 8 cores CPU). The form itself is not very long, it has about twenty questions. ## Steps to Reproduce Create a form, share it with many users and at some point, the sharing will become very slow. ## Expected behavior The form sharing operation should be optimized for a large number of users and the system should be responsive during the operation. ## Additional details https://community.kobotoolbox.org/t/slow-sharing-permissions/11351/3

It’s in the pipeline to make this more performant. Please refer to the advice here in the meantime if you are sharing many forms through the UI:

You should however be able to use the API for managing form permissions (or even through the Django shell) as a work-around.
