Evaluating a multiprocessor NT server for Z39.50 use
OCLC's FirstSearch Next Generation research project is investigating the use of Java and Microsoft's Windowsʼ NT operating system as a platform for a Java-based Z39.50 retrieval system. We have conducted a series of low-level benchmark tests of both random I/Os and socket throughput under varied parameters. The maximum disk read rate for each server is from 410 to 1,350 random reads/second for block sizes of between 32K and 4K, respectively. Each NT server can provide a connection rate of 110 transactions per second for transaction sizes up to 32K and a maximum connection rate of 190/second for smaller transaction sizes.
