compression

I'm trying to find a balance between performance and degree of compression when gzipping a Java webapp response.

In looking at the Deflater class, I can set a level and a strategy. The levels are self explanatory - BEST_SPEED to BEST_COMPRESSION.

I'm not sure regarding the strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY

I can make some sense from the Javadoc but I was wondering if someone had used a specific strategy in their apps and if you saw any difference in terms of performance / degree of compression.

Thanks, Keyur
