The goal of DAVID's design is to be able to efficiently upload and analyze a list consisting of <=3000 genes.
All DAVID tools have been tested with lists in this range and should return results in a few seconds to no more than a few minutes.
If running time is longer than a few minutes, please contact the DAVID Bioinformatic Team for help. Please note that Functional Annotation Clustering and Gene Functional Classification have a 3000 gene limit.
