The Linux file cache really helps. The simplest approach is to just "cat" the index files to /dev/null a few times an hour. Slightly faster (what I do with Solr) is mmap the files into memory and read a byte from each page now and then. Assuming (as in Lucene) that the index file format is compressed, this approach is far more ram-efficient than actually unpacking the index into data structures. though of course you take the overhead (a few microseconds) of a couple system calls at each access to the index even when it's all in cache. -- http://mail.python.org/mailman/listinfo/python-list
