I hope to improve response speed as much as possible, and I test the time my drawing function, which spends 2.9~3.2 seconds.
Any tips to improve the speed are appreciated, from algorithm, program, website design...

The during time between 'user click draw button' and 'show picture in browser' is too long, using python and django, how can I reduce the time? Thanks in advance.

If it is a long running task,

you can try,
Using Celery with WebSockets

You can initiate a celery worker (refer here) to do the long running job and return the
results via websocket (django channels)
