No tuning will eliminate gcs. 20-30 seconds is horrific and out of the ordinary. Most likely implementing antipatterns and/or poorly configured. Sub 1s is realistic but with some workloads still may require some tuning to maintain. Some workloads are very unfriendly to GCs though (ie heavy tombstones, very wide partitions).
