Is there a way to increase AS memory beyond 4096MB? How can we find out the best setting?

Help > Edit Custom VM Options
Mine for example:

# custom Android Studio VM options, see <https://developer.android.com/studio/intro/studio-config.html>
-Xmx8192m
-XX:MaxPermSize=4096m
-XX:ReservedCodeCacheSize=2048m

8GB heap size.

Do you notice any diference compared to the default values?

XX:MaxPermSize

looks like it was removed in Java 8

[wbertan]

Could be, as I've copying this around for a quite some time. 😬
The performance, well, for me at least seems better than not setting it.
Especially when I usually have 2 or 3 Android Studio open 👀
Everything is still fine and works reasonable quick.

sometimes I have many projects open simultaneously too, the max heap size is applied to each AS instance as I understand. right?

[Sergio C.]

8x(Many AS) can be a lot of memory

[Sergio C.]

need to try it to see what happens.

[wbertan]

No 🤔 Here it is shared, they all show the same amount of memory in the corner, and if I clear in one, show the decrease in all others too

[Sergio C.]

looks like so

[Sergio C.]

opened 4 projects and max used memory was bellow 4GB

lets bump it up
