Thanks Ian! I tried again and it seems to work now.

A couple of threads that have helped me:

Tips to speed up app startup

Hey guys! I’ve built an app on Anvil that I’m about to launch commercially, in which I have around 10 client-side forms and 6-7 Server modules; so on each startup, the app takes around 2-3 minutes to load. The app has around 10 external libraries installed, and each server module calls atleast 3-4 of those libraries. Does anyone know how I can speed up my app’s startup?

Help me with Decision about increasing Application speed

Dear Formers ! First of all, Thank you Anvil for opportunity to become full-stack web developer with knowledge only Python! It was great experience for me to build my own web application. My application is almost ready and now I should make decision about how to increase the Speed of running of web-application - it is running too slow - users will not accept this. Now I thinking about several alternatives to make right decision: Buy my own server Pro: no monthly charges Cons: additiona…

Moving Beyond Anvil (General Discussion)

Definitely appreciate your input Rufus, it’s great to hear from people who have already trodden paths that I am currently looking to be going down. I agree with your conclusion regarding Anvil’s UI needs more massaging as you go on and it makes managing things hard. I haven’t gone as far as rewriting the Bootstrap classes, but definitely struggle to wrap my head around it and the best way to approach issues Based on suggestions here, Flutter seems to be the UI framework that I am leaning toward…

Hosted solution scalability

Hi @jamesghutchison, Roughly speaking, there are three tiers of Anvil plan: Free, Personal, Professional and Business plans all use fully shared hosting. All your traffic is handled by shared servers; your Server Modules run in the same place as everyone else’s; your Data Tables data lives in shared databases. We do our best to enforce fairness, so that “noisy neighbours” don’t affect your app’s performance, but ultimately these are all shared resources. Because everyone is using a shared fl…

Why does a server call from the client take longer than the server code takes to run?

Hi, @shanhewang, and welcome to the Anvil Forum! It depends on what your code is actually doing. Each program creates its own distinct patterns of activity. Some steps can be slower than others, especially if they’re repeated many times. And it’s not just database activity that can slow things down. For example, my own server-side code was needlessly importing some very large files. Now, I postpone importing them until absolutely necessary. That reduced server-side startup time on every …

Very slow database performance

Hi With everyone’s help I am making good progress on my basic CRUD app. However, the data table performance is excruciatingly slow. I have a simple data table with ~500 rows and I really expected that populating the datagrid will be snappy. But it is not. I tried returning a dictionory as suggested by @alcampopiano in another post, but that did not help. I am not very savvy with timing functions etc. but it is very apparent that it is slow. I am a paid user and below is the clone link. See…
