The Pablo Java I/O Performance Capture Facility (Java PCF), is a package designed to capture the I/O activity of Java 2 codes running on Windows systems. The code is written in Java 2 and should be easily ported to other operating systems with Java installed. Pablo Java PCF support the use of threaded code enabling for recording captured performance metrics. of file I/O operations for the FileInputStream, FileOutputStream, FileReader, FileWriter and RandomAccessFile Java classes.
The Java PCF records metrics from I/O operations to trace files written in the Pablo SDDF format. The SDDF trace files can be analyzed using the same analysis tools designed to produce statistical reports for the Unix I/O activity.
The following links describe how to used the Java PCF and how to obtain the software.
