CPU utilization is going 200% and above when I am working with Android Studio, How can over come this ?

[gildor]

check what kind process it is (run jps -mv

[gildor]

probably it’s Gradle daemon
But it shouldn’t consume so much CPU if it idle, but it’s fine if build in process]

[Chethan]

Here is the response of jps -mv

[gildor]

Yes, as you can see it’s Gradle daemon

[gildor]

if you do not build anything, it’s a bug, something causes consuming CPU while daemon is idle, you can try attach profiler and check

[Chethan]

I am building project , every time I try to run , takes about 5 minutes

[gildor]

If you building it’s fine itself, Gradle will run worker on every core of your CPU by default, will try to run them in parallel as possible

[gildor]

so you problem is not CPU consumption, but build time?

[gildor]

First I would recommend to run Gradle Build Scan and check what consumes most of the time, how long GC time and other check other recommendations

[gildor]

anyway, build time is very big topic, it’s a lot of materials in internet

[Chethan]

I am not sure where the problem laying , I can't even browse other application when this is going up to 200% , other application also freezes

[gildor]

Makes sense, Gradle tries to consume everything what is available

[gildor]

also check that you have enough memory and not in swap

[Chethan]

I have 16gb RAM , processor is core i5

[gildor]

it’s not very fast nova days 🙂

But anyway, I mean that you should check that you are not in swap

[gildor]

open memory tab in Mac Monitor and check amount of free memory and swap size

[Chethan]

Here it is

[gildor]

Tight, but looks mostly fine

[Chethan]

how much you would think should be available for swap size

[gildor]

So if you problem just issue that during build Gradle consumes too much resources you have 2 ways: reduce amount of workers (org.gradle.workers.max option) or try to use org.gradle.priority option: https://docs.gradle.org/5.0/release-notes.html#gradle-can-be-started-as-a-low-priority-process

[gildor]

but you should understand, it will probably increase your buiild time

[gildor]

how much you would think should be available for swap size

You should have close to zero, so nothing in swap, but actually OS still uses it, so it never 0

[Chethan]

oh .. but it has taken 2 .6 gb size

[gildor]

yes, but it’s about 15% of your memory

[Chethan]

Let me go around all the possible options , find out what exactly causing this issue

[gildor]

anyway, if you are on swap, so OS doesn’t have enough physical RAM it will use disc instead, which makes everything a lot slower (disk obviosly a lot slower)

[gildor]

I would first decide what you trying to fix there %)
