然而我的主要问题是，为什么同一个查询在双核系统上比在单核上运行得慢？
However my main question is really, why should the same query now run slower on a dual-core system than on a single-core?
由核密度估计推导获得的高斯核均值漂移算法因收敛速度慢在应用中效率不高。
The Gaussian kernel mean-shift algorithm which is deduced from kernel density estimation has not been widely employed in applications because of its low convergence rate.
