DSEE 7 Compression Squeezes Out More Performance

In December and early January,Download DSEE free of charge Brad Diggs took DSEE 7.0 into Sun's Benchmark Center to evaluate performance and scalability on Sun's latest hardware including F20 PCIe flash cards.

Brad's first write up describes how much DSEE 7 compression rocks, "Reducing storage footprint by more than 50% and extending search performance by more than 50%." All the key results are explained in detail. Brad provides the commands to run to get the benefits from DSEE 7.0 in your lab or production environment. A must read for all of you aiming to get the best results from Directory Server 7.0, and to get the most out of your server hardware.

Comments:

Ludo has done a quicker study with OpenDS 2.2 using entry compaction and compression as well. See http://blogs.sun.com/Ludo/entry/sun_directory_compresses_data_for on his blog.

In Ludo's example, compression saved almost 10% DB size versus compaction alone, although it does prolong import time. But it can be a good way to save space if most of your entry values compress well (e.g. are strings).
