Speed-up application by remove code for writing logs?

Question

I am trying to speed-up my application. Will it make my app significantly faster if I remove all the logs-code? Does it make a difference ?

My app writes lots of logs.

Log.v(TAG, "example android log");

I read this question , but it doesnt answer my question.

Answer 1

No, it won't make any visible improvements on your perfs.

Unless you're doing really bad things such as:

• Non-stop logging (100x every frame)
• String concatenations
• toString() method calls
• any object allocation

Maybe you could share some snippets of your logging code to see if there is anything wrong.

Answer 2

Depends on the functionalities of you Glass app. If your glass app is just a slideshow there are different aspects that needs to be taken care of than a Media Streaming app. Offcourse, reducing the number of log statements would help a bit in the performance but there are other significant points that should be taken into consideration.
