Some time ago I compared some indexers and databases and database-like systems for some text retrieval system I was going to make on top of them. It turned out that systems based on databases were by far the slowest and systems based on custom data structures by far the fastest. We're talking orders of magnitude of difference, such that using something like an index based on PostgreSQL (reputedly a very good SQL database) was absolutely unusable (took over a day to process my test set while grinding the disk to death, then I terminated it), where an indexer with completely custom structures did the work in a not so large number of minutes. It is obvious what I chose after that experiment. -Olaf. -- ___ Olaf 'Rhialto' Seibert -- You author it, and I'll reader it. \X/ rhialto/at/xs4all.nl -- Cetero censeo "authored" delendum esse. _______________________________________________ Pan-users mailing list Pan-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/pan-users
