@farhanlatif027i3df This should probably get moved to the “slow blocks” thread. or any of the following really.

> I think Thunkable x is cool it lets you make app for iOS and android but the lag is unbearable I have to wait 20 min. Exact 20 min for it to start my block screen then for every movement I do I have to wait 10 min additionally I wanna do so many creative things with my app but how can I when the lag is so so much I actually wanna cry when I realise I have to go back in blocks section to fix something I hate the lag so much

> I have a screen with a large number of blocks. The blocks execute fine on my device so everything is working great, but the Thunkable block editor on my PC is very laggy. Anytime I move or modify a block, there is a delay before I am able to move or modify the next block. When checking the javascript console, there are a very large number of errors “unable to find component with id null” that are being logged while the site is unresponsive. Is there any way for the Thunkable team to trace the s…

I was just at one of my worksites today where they have a google fiber connection. My project had near 0 lag. I am now at the local library and my block editor is lagging slightly. When I am at home, the lag is only slightly more than here at the library.

I really think that the lagginess we experience is a function of both the constant updating but also our individual internet connections. The better my internet connection, the less i feel the need to optimize blocks 😂 (but it’s still a good idea to optimize because i have to go home to my slow internet eventually)

I spent most of yesterday optimizing and was able to remove 400-500 redundant blocks through the use of FUnctions. One day, when the anycomponent blocks make sense, I feel I will be able to reduce the block usage even more!
