Optimal Buffer and Destination Byte Array Size for java.io.BufferedInputStream Reads (for a slow disk)
Earlier in the week I ran some micro-benchmarks against my new very performant Intel X25M solid state drive. Today, for 'kicks', I ran the same benchmarks with the same data against a 5,400 RPM external USB-attached 3.5" hard disk drive. Wow, what a ... |

Optimal Buffer and Destination Byte Array Size for java.io.BufferedInputStream Reads (for a fast disk)
When implementing file reading Java code with Java IO's BufferedInputStream, what buffer size should one choose? Should we just not specific it and go with the default? And what destination byte array size is best? These questions pop up from time to ... |

Real world performance metrics: java.io vs. java.nio (The Sequel)
The first set of results (September 2008) measuring the performance improvement gained by the switch to java.nio for FLV indexing were not particularly scientific. Each data point was from a different file, of dramatically different sizes, with ... |

Real world performance metrics: java.io vs. java.nio
In my application at xtendx AG, there is some code that indexes uploaded FLV (Flash video) files to determine the byte mark of each key-frame which are spaced out every second or so by our encoding process. The index allows client players to request an ... |
