Don't copy interesting ids, clean up logging (#11102)
When searching the caches don't copy the ids, instead inline the loop.

```
Benchmark_bucketMetacache_findCache-32    	   19200	     63490 ns/op	    8303 B/op	       5 allocs/op
Benchmark_bucketMetacache_findCache-32    	   20338	     58609 ns/op	     111 B/op	       4 allocs/op
```

Add a reasonable, but still the simplistic benchmark.

Bonus - make nicer zero alloc logging
