Sean, Params = field values, it is always link_la_typ.lat_typ_id and link_la_typ.lat_ga_id i search, but always with diferent params.
OS is Win7 x64 - its my development machine. I plan to put database on win2008 R2 x64 server wit 20GB RAM. I dont know what is depth of an index.Index is created as CREATE INDEX _LINK_LA_TYP_IDX5 ON LINK_LA_TYP (LAT_GA_ID, LAT_TYP_ID); I hope this helps. Zoran
