Networks have two primary characteristics to consider: bandwidth and latency. If Sybase Search is installed on multiple servers, reducing the effect of any network lag improves the performance of indexing.
For example, closer the source documents are to the container that does the indexing, better are the performance results. If source documents are on a different server than where indexing takes place, each document must be copied across the network for analyzing and processing. If possible, place all documents on the same server to remove any network effect.
Similarly, for database imports, the faster the database connection to the satellite container, the better your performance is, since the speed of the JDBC call to the database depends on network speed.
