Hi,
I am using Jdeveloper Studio Edition Version 12.2.1.2.0 on a Windows 10 64 bit platform with 16 GB RAM, it seems terribly slow and laggy so much so as I would say almost unusable, navigating into different files takes an age, writing code takes an age(it seems to be checking something in the background). I have tried the usual steps of changing the look and feel to windows, increasing the memory in ide.conf and jdev.conf, disabling features and disable build after save options. Is there anything else those with Windows machines have tried? I heard the anti-virus might be a problem but as on a corporate system the anti-virus is prescribed on the PC. I have seen it used on a MAC and the experience is a world away.
