Starting on 1/1/2010 Symantec Endpoint Protection Manager v11, the software that pulls down updates from Symantec and pushes them out to all the client systems, started repeatedly downloading the same virus def over and over and stashing them in randomly named temp folders on the C drive at the rate of about 1GB/hour. Party. Lots of folks on the Symantec support forms are experiencing the issue. Purging the temp folders and upgrading to the recently released v11 RU5 fixes the problem, but those without current support contracts to get the updates would be kinda screwed...

Luckily today was a slow day at work so I did various benchmark tests both before and after installing SP1. This was all done on my Dell Inspiron E1705 laptop, Core 2 Duo 2Ghz CPU, 2GB RAM, and a freshly defragmented 200GB 7200RPM Seagate HD. Not a mobile Lan Party screamer, but it gets the job done well enough.

Boot times dropped, both with and without ReadyBoost enabled (using a 4GB 150x SD card) by about 10 seconds, ending up with 1:56 clean and 1:45 with ReadyBoost.

ATTO Disk Benchmark showed a .

Copying 1GB of JPG files from one partition to another dropped from 1:31 to 1:09, and to the network from 1:35 to 1:06.

3DMark06 scores very slightly increased, PCBench05 scores slightly decreased.

The graphics test in CoH OF went from 59.7/28.8/7.9 up to 59.7/28.9/9.2

So no huge improvements, but overall things are just a bit more snappy.
