Of course. To build an access path you have to page in all the data and if
90 pct of what you are getting is deleted records it is going to take
longer.

Hi,

Is there any substantial difference in the time taken to build an Access
path for a new logical file if the physical file has a high number of
deleted records.

The file I am concerned about has only about 4.5 million records but it
also has about 300 million Deleted records.

All other things being equal, would the time to create a new logical
differ, if there were no deleted records?

TIA
Vinay
