. The latest results are 5400 faster than the previous Intel Xeon 150% results. Cisco and Red Hat Benchmark Cisco and RedHat show the performance of Cisco's Unified Computing System, the latest server on the market. The test results exceed 154% of Intel SPECopmMbase's previous score. This new type of Blade Server from Cisco took the lead in two systems just two weeks after its launch. The

Five tips for Instagram to improve PostgreSQL performance, postgresql Performance Optimization As Instagram grows, Postgres continues to serve as a solid foundation for Instagram and stores a vast majority of user data. Less than a year ago, we also wrote on our blog that Instagram "stores a large amount of data" and a

doubled. For details, see Test 3. 4) The Memory parameter is added so that the content of the entire database table can be basically stored in the memory. The performance is improved significantly by over 50%. For details, see Test 4. 5) when the memory can be loaded into the entire database table, increasing the memory parameter does not affect the performance improvement. See Test 5. 6) When prewrite log

, although 5.6.5 made a significant improvement, but PostgreSQL support table connection is better, especially MySQL does not support the full outside connection, therefore, this aspect of PostgreSQL better than MySQL; JSON support and Nosql:postgresql have recently added JSON support, which provides greater data storage flexibility than a traditional relational database, so

, and the V1 on the sort is almost 3 times times the V2. Further testing, if added limit ... offset (often used with order by for paging), the gap between the two view is more pronounced: If you remove the sort operation, the V1 query will take more time than V2, but it is almost an order of magnitude less than before. Confined to space, this place does not map. The number of records in this test is less than million, you can see the gap between the two views, interested peers can self-verify

Oracle and postgresql join methodFirst, we will introduce several oracle multi-Table Connection Methods:Nested loop: nested loop, which is actually a dual FOR LOOP1. The driver table (External table) and search table (internal table) are divided here)2. To search for a table with an index, you can use an index to find and match the table, improving the efficiency
