Paper Abstract:
|
There are several articles which suggest certain improvements in the performance of Web searches by means of
techniques such as index distribution. Other articles analyze which are the bottlenecks of this performance (imbalance
among query servers, network load when results are being sent, reordering of these results at the broker, etc.).
Nevertheless, most of these works have only made use of simulation methods in order to perform the experiments, but the
results have not been checked in a more realistic environment.
In the current article we submit an example of an information retrieval distributed system and we show the results of
some experiments performed by means of the aforementioned system in order to check that it can be used to find out if,
in practice, the techniques analyzed in several studies improve the performance in Web search and how certain factors
(broker, the slowest query server, etc.) have an influence on the system. |
