JDeveloper is slow on Windows 10

Yeah, it is slow! The version of JDeveloper is Studio Edition Version 12.2.1.0.0, OS is Windows 10 Pro with 16 GB RAM, core i7 CPUs and still it is slow.
I have done all the possible tweaks, none helped so far.

The same works with no delays on Windows Server Standard (although not certified), no issues with the performance....

An update.
Finally, after I have changed some BIOS settings, namely disabled "Intel Speed Step" as well as "C-States Control" settings the JDeveloper now works at acceptable performance levels. I have to admit, that there still some random freezes, but this may be related to  the project itself.

Because of lack of time, I have not checked which setting out of two has made such a significant change.

JDeveloper 12c (12.2.1) and MySQL database

I have started a project where I plan to use MySQL (

5.7.11, community edition) as a data backend. I use JDeveloper 12c (12.2.1.0) to develop model, UI etc. The first problem I faced is that JDeveloper does not correctly add associations (therefore, create viewlinks) between tables. This is described in this entry https://java.net/jira/browse/ADFEMG-142 but for earlier versions of JDeveloper and MySQL, but the issue is reproduced in JDeveloper 12c as well. Unfortunately, the reported bug has no resolution. To resolve the issue, I had to manually create or adjust the associations and viewlinks.
