双语例句
- Because the index is used to access the table, I/ O is more efficient.
由于索引是用来访问表的，所以I/O会更加有效。 - Although this lookup is done via the primary key index, it does take CPU cycles to do the search, and possibly I/ O to read index page ( s) into the buffer pool.
虽然这种查找是通过主键索引进行的，但是这仍然要占用CPU循环来进行搜索，而且可能还要占用I/O将索引页读入缓冲池。 - Later on we'll discuss index maintenance, but for now just keep in mind that the buffer pool and I/ O considerations for inserts apply in a similar manner to index pages as they do data pages.
晚些时候我们将讨论索引的维护，但是现在只需记住，插入时对缓冲池和I/O的考虑也类似地适用于索引页，对于数据页也是一样。 - The first feature that makes this release really stand out is index compression, which reduces both I/ O and the size of the index structure.
这个版本中最引人注目的新特性之一是索引压缩，这会减少索引结构的I/O数量和大小。 - Proper index can help DBMS fetch the data quickly; reduce the cost of I/ O, so the proper index also play a great role for optimizer.
索引能够帮助数据库管理系统快速定位数据，减少I/O的消耗，合理的设计索引，在数据库优化时也会起到不可或缺的作用。 - Either Video Server or Index Calculation System has strong requirements of computation performance and I/ O throughput, besides that the systems must be reliable.
无论是视频服务器还是指标计算系统都对系统的计算能力，I／O读写能力有较高的要求，同时还有可靠性的要求。 - The default index means Lucene provides is to build index files on disk with single indexer. This would frequently execute I/ O operations which result in low efficiency of indexing.
Lucene提供的默认的索引方式是通过单个索引器在磁盘上建立索引文件，这样会频繁的进行I/O操作，导致建立索引的效率下降。
