 In a test setup with looping through 100 DataObjects each with 100 related DataObjects for a total of 10,000 records per test run, the following performance improvements were observed for different types of relations (eager-loading vs not eager-loading):
 
-- HasOne - 3227% faster (0.0078s vs 0.2595s)
-- HasMany - 25% faster (0.1453s vs 0.1819s)
-- ManyMany - 25% faster (0.1664s vs 0.2083s)
-- ManyManyThrough - 16% faster (0.6586s vs 0.7681s)
