Reference: see CR#6378768 as reference bug.

Part of 1.5.0_07-b02 PIT Testing.

(on a 1.8GHz/512MB system running win-2000-pro with SP4)
using 1.5.0_07-ea-b01: 55s, 55s, 56s, 56s, 56s. Average = 55.6s
using 1.5.0_07-b02:    62s, 62s, 62s, 61s, 61s. Average = 61.6s
difference of +6s.

(on a 1.8GHz/1024 system running win-xp-pro with SP2)
using 1.5.0_07-ea-b01: 64s, 64s, 64s, 64s, 63s. Average = 63.8s
using 1.5.0_07-b02:    68s, 69s, 69s, 70s, 68s. Average = 68.8s.

Both systems are dual-boot and can be slow sometimes.

Comments
EVALUATION In 5.0u7 b02, we introduced 2 bug fixes which reduced the download size by almost 2MB. This savings will happen with all JRE downloads (offline, online and updated). There was a slight trade off that it slowed down the JRE installer by ~5 seconds on slower machines. Computers are still faster than networks, so this was a worthy tradeoff.
