This doesn’t make sense to me.
IntelliJ gained popularity almost entirely because it was so much faster than the alternatives. I started using it back in 2005 when I was doing Java work and Eclipse or Netbeans were the other viable options. They were both so slow they were unusable and would eventually bring my entire machine to a crawl.
IntelliJ by contrast was so fast I couldn’t believe it and it’s always continued to be fast. I’ve used RubyMine heavily over the last few years and just recently switched to IntelliJ Ultimate because I’ve got so many languages plugged in that it just made more sense…but it’s been zippy every step of the way.
The only time I ever had a performance issue was after I switched to Fedora I noticed that startup times were around 20 seconds long and it turned out to be because of lack of a hostname reference in /etc/hosts. Soon as that was taken care of, everything was great.
