Table 1 Computational experiments for evaluating QoDisco

To assess the influence of parallel searches over repositories on the performance of synchronous searches

To assess the performance of QoDisco upon an increasing number of records queried in a synchronous search

To assess the performance of the asynchronous search process with a varying number of clients to be notified about the publication of a new record in a repository

To assess the performance of the asynchronous search process to notify a single client with a varying number of records published at the same time
