Try running their products on a more recent JVM. They are actually usable and don't leave you feeling like you've been thinking in molasses. Ironic for a company called "jet" brains.
They (JetBrains) have been actively fucking a portion of their (one would think, technically savvy) customers by not giving them the most responsive system they can to run, then acting all paternalistic and gaslighty by saying "oh we don't recommend you use anything other than the one we ship." [1] when people complain.
Listen, JetBrains: I have wasted enough time (while my thoughts race ahead trying to work on my projects) sat on my phatass 64Gb NVMe-equipped Xeon, nvidia (native driver) Debian workstation waiting for pycharm et al to mooch along like at a stately pace redrawing the screen like it's a 1994 486 with an HDD. In the end my thoughts stopped racing and I began to think, yeah, well, I just gotta endure it... and then asking myself if I'm alone in this particular slow-motion hell-hole or is the world really like this?!
Once I had got to the bottom of it (notes here https://iam.georgecox.com/2021/11/24/making-jetbrains-ides-r...) I _instantly_ began to regain the feeling of fluidity of thought in my work. It was the biggest single productivity gain I've made in the past year, and I have had zero stability problems. Some debugging features are not available, but I haven't missed them.
At this point JetBrains would do well to take a leaf out of Apple's playbook from 2009 when they shipped the Snow Leopard release (Yes I am one of those that thinks that Snow Leopard was the best release of Mac OS X...) which concentrated solely on quality and speed, and no new features. [2]
Thank you for your attention. Merry Christmas ;-)
[1] a fact which gets parroted around various fora without any understanding of the problem because "it works on their computer" It seems that much of the improvements are for the benefit of MacOS X users, while the policy of sticking with a version 11 JDK is to the detriment of users on other platforms.
[2] quality and speed are features, too!
