Identify three reasons that explain why assigning more than one managed serve achieve better performance than running one managed server with more resources?（）
A
Thread management inside the JVM process might be less effective than context switching between processes on the OS level. It is better to combine both these technologies to achieve full saturation of resources.
B
Current CPUs are multicore units. So starting managed servers in the amount of physical cores and pinning them 1:1 to cores will always get the best performance.
C
By a combination of prioritization of processes on the OS level and Work Manager in WLS, one could tune the whole environment more precisely.
D
Assigning more than one managed server to hardware will never bring better performance.
E
More instances means more connections to databases, so one could serve more concurrent calls on the database level. This is primarily why this approach will give better performance numbers.
F
Depending on the profile of the application, having more JVMs with smaller heaps will lead to more predictable response times than fewer JVMs with a large heap.

A recent US study found that people who score high for extroversion rate themselves as leaner and taller than they acmally are,with male extroverts weighing more than introverts.Conscientiousness is associated with a healthier weight,xvith the most conscientious（in the top 25%）weighing on average almost Skg less than the least conscientious（in the bottom 25%）.Participants scoring low on emotional stability tended to overestimate their weight,although women who gave themselves a low score did actually weigh more than others with higher scores on this trait.These findings held across all of the ethnic groups included in the study.While some links are unsurprising（eg.conscientious people stick to their diets）,some are not so easy to explain.Why,for example,do extrovcrted men weigh more?Is it because they're always in the pub?If so,perhaps the"beer goggle"effect explains why they rate themselves as taller and thinner than they actually are.
