如果要执行更复杂的查询,或者要连续执行多个查询,那么执行时间的差距就不是次秒级的,而是以秒甚至分钟来计算的。
If more complex queries are executed, or if several queries are executed in sequence, the difference in the execution time is not just sub-seconds but seconds or even minutes.
因此,执行时间上的差距并不是很明显。
Therefore, the differences regarding the execution time seem to be irrelevant.
But if you look at the tech fund category, the difference between the dollar-weighted and the time-weighted returns--this is over a ten-year period -is 13.4% per annum; that's stunning.
但是如果你关注科技投资基金,十年间,货币加权回报率,和时间加权回报率间的差距,是每年13.4%,这是非常夸张的
