Download Manager pegs 1Ghz CPU at 90% for 45 seconds to download a file

User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; rv:1.7.3) Gecko/20040913 Firefox/0.10.1 Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; rv:1.7.3) Gecko/20040913 Firefox/0.10.1 Running Firefox 0.10.1 on a PowerBook G4 w/1 Ghz CPU & 1GB RAM. Mac OS X 10.3.5, Java 1.4.2 update 2. When I download a large file (like a 3 MB PDF), it takes a long time for the download manager to start and execute the task. During this time, the system CPU goes to 90% and remains there until the download is complete and the download manager quits. If this is expected startup overhead for invoking a download manager that hasn't been instantiated, I'd suggest offering the user the option of instantiating the download manager on Firefox startup and not each time the user downloads a file. Reproducible: Always Steps to Reproduce: 1. Download any large file using the above setup. 2. 3. Actual Results: System CPU goes to 90% while the download manager is running. Expected Results: Consume a reasonable amount of CPU
Seems to show the JVM getting instantiated. If so, this is alot of overhead to go through each time a user needs to download something.

This does not seem like a dupe of that bug at all.
