>did you perform these deletes on the same dataserver with the same configurations
All result are taken from the same ASE server and database.
> are you by any chance running the non-part test with more options enabled (eg, 'set statistics io on' enabled for non-part test but disabled for the part test)? if you are running with any settings enabled (eg, 'set statistics', 'set showplan', etc) could you try running both tests with no extra settings enabled? [some settings ... like 'set statistics' and 'set showplan' can add considerably to your total cpu/logicalIO counts]
All deletes have been executed with "set statistics time,io on". Checking the settings of the shell script show that all results for both tables have been executed with the same settings.
