Comparison of database search speed. Search time versus query sequence length is plotted for the different search programs and the 11 query sequences (see Results). The search time used is the total CPU time of the fastest of three consecutive runs on a minimally loaded computer. With a database of only 29 and 128 MB of RAM, all of the database was cached in the computer’s RAM; disk reading time should then be negligible.
