Performance Analysis of a Single-file Version of Linear Hashing

P.-A. Larson *

Department of Computer Science, University of Waterloo, Waterloo, Ontario, Canada

A performance analysis of a new variant of linear hashing with partial expansions is presented. In the new variant the overflow area is combined with the prime storage area in the same file. The performance measures considered are: expected length of successful and unsuccessful searches and cost of insertions. The new method uses several overflow chains per page. Increasing the number of chains significantly improves the retrieval performance.
