分裂树 meaning in Chinese

splay tree

In order to improve system performance , a general cache to preserve access control information is built upon split trees inside the secure kernel
为提高系统性能，可以在安全内核中创建一个以分裂树为基础的访问控制信息通用缓存。
Our data discloses that the hash - table and dynamic tree splitting operations used in crafty have caused huge l3 cache misses which at last bring in large scalability penalties . they consume 35 % ~ 50 % of the running time on our 4 - way system . by comparison , similar functions of prbfm only cost about 20 % running time
我们的试验数据表明crafty中哈希表操作和动态分裂树操作导致的l3cachemiss成为其多线程程序下的性能瓶颈,导致了极大的扩展性问题,在我们4路和16路的并行系统上,这些操作的时间占到了程序运行总时间的35 % ~ 50 % 。
