Slowness when executing "Extract Multi Values to Points"

has anyone notice the slowness when executing "Extract Multi Values to Points" tool in ArcGIS 10? It takes at least 3 minutes 20 seconds to run a shapefile that has 7000 records against a raster data. I also tried to run "Extract Values to Point" tool (which create a new shapefile with extracted value). It runs only 7 seconds and produced correct results.  The results of the extracted values that are outside of the raster data for "Extract Multi Values to Points" create "0" as null value, but in "Extract Values to Points" create "-9999" as null value. The oracle database, read "0" as a value not null. Does that consider a bug?

I need to run the my shapefile against 12 raster data with "Extract Multi Values to Points" tool because I don't want to create new shapefiles for every raster that I am extracting the value from.
Is there any alternative? or fixes on this?

Thanks,
Linda
