Fix description: When the idlist size is larger than nsslapd- lookthroughlimit, the range search returns ALLID (default value of nsslapd-lookthroughlimit is 5000). Then, the range search filter is evaluated before returning to the client. If the default value of nsslapd-lookthroughlimit can be used, the search elapsed time is much shorter than generating a complete idlist in index_range_read_ext. Since the nsslapd- lookthroughlimit is shared among all the search operations, larger value might be required for other cases. To have its own control, this patch introduces a new config parameter nsslapd-rangelookthroughlimit for the range search. Also, this patch replaced idl_union in index_range_read_ext with idl_append_extend and sort the idlist at the end. It improves the range search performance, but it is still slower than just returning ALLID for the large db. -- 389-devel mailing list 389-devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/389-devel
