Answer 1

GC_CONCURRENT

Means that Garbage Collection happens in a parallel manner. Without affecting any performance.

freed 440K

This particular cycle of GC has freed 440k memory.

free 3317K/6471K

Available and total Heap Memory Details.

external 0K/512K

External Memory available for your app(other than heap).

4ms+7ms

4ms at the beginning of GC was paused and at the end 7ms was consumed by GC.

That is, during this GC, all your activities were suspended for a total of 11ms , 4ms at the beginning and 7ms at the end.

For more info on this, please watch this video. He explains this very clearly.

Answer 2

Indeed. It shows that garbage colector was fired ( which happens on regular basis) and it could reclaim 440K of memory. Whether it is a lot or not depends on your application, but less is better. Rule of thumb is to avoid memory allocation whenever possible.
