Hi, This is my first mail to this list, so please bear with me. I'm a computer science student doing a thesis on paging algorithms, both from a theoretical and practical viewpoint. I'm currently looking for some standard way of testing the performance of paging alogrithms. But I haven't been able to find any paging benchmarks anywhere (both in the literature and on the web). I would therefore like to know if the developers of postgresql are doing any kind of paging benchmarks? And in case there are, I would like to see them. It could also be that someone not a postgresql developer, knows of some paging benchmarks. If there are, then I would very much like to know. Thanks in advance, Martin ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
