3. Hibernate: Performance issue vs JDBC coderanch.comWell, remember that all calls to Hibernate get translated to JDBC before they go to the database. Hibernate and JDBC are tied pretty closely together. Having said that, there are always optimizations that people that know SQL well can do to make their database queries hum. Hibernate doesn't invalidate the JDBC Java packages, so you can always call JDBC code alongside ... |
4. JPA and JDBC, Which one is Performance efficient coderanch.comHi I am working on an application that needs to be highly performance efficient. We will be having heavy data stored in data bases. And will be having hundreds of requests per minute and for each request will interact with database. Now JPA ease us from writing SQL and many more, but in this sceneraio, will JPA be that efficient as ... |
5. Hibernate Performance compared to JDBC forum.hibernate.orgHi, I have written two sample programs one with hibernate and another JDBC. The program just looks up at a table and does a range scan and gets only 5 records out of 100,000. I am doing this 1 million times inside a loop. To my surprise hibernate takes more than 3 times that of JDBC. Can anybody let me know ... |
6. "Read only" performance compared to JDBC forum.hibernate.orgI am running a test with Hibernate and direct JDBC to read data from one table. I am using DB2 and Hibernate (2.0.3 and 2.1b6). I am running the test in a loop and reading all the data in one table (1000 records). The persistent Object contains only 3 (String) attributes. I used test class similar to net.sf.hibernate.test.PerformanceTest. JDBC is 2.2 ... |
7. Performance comparison with JDBC forum.hibernate.orgI'm doing a performance evaluation of Hibernate w.r.t JDBC and I find that in many cases Hibernate is a lot slower than JDBC - the Hibernate web site claims that the overhead is in the region of 10%. When I do very simple queries on an object that maps to a table - no joins involved and nothing fancy I find ... |
8. Huge performance hit compared to raw jdbc forum.hibernate.orgHi all, We studied many frameworks for the database layer of our architecture and choosed hibernate. The application is a really large, clustered e-commerce system that must cope with HUGE amounts of traffic. To make things even worse, the traffic comes in bursts at certain times. So one of our main points why we decided to go with hibernate was that ... |
