I've never had it take 5 minutes on a ~3 year old Intel i5 with a cheap SSD. Maybe 10 seconds. Scanning a large project might take 30-60 seconds. 5 minutes would be painful. What kind of set up do you have and what size project?
I find startup time of PyCharm to be really stochastic. Sometimes it's 10-20 seconds and sometimes it takes a couple of minutes, even on relatively tiny projects.
That being said I think PyCharm is good enough that I'm willing to put up with that.
core i3 with hdd
How many times per day do you start it?
changing python 2 to 3 projects cause "indexing"
I don't have ssd to make it faster
