Default Memory usage with new version

Hi, I've just updated to the new version and works fine, but memory usage increased a lot. Now is taking 549.764KB. Previous version was a little memory hungry, but not that much.
Any tips to reduce the memory usage ?

Thanks

gotta agree with you. On the new version. the memory footprint has pretty well doubled.

Far more worrying and a much worse problem - the cpu usage has gone from a few percent, to at least 30 (when just d/ling), up to 100% and locking up the whole machine. Above about 60% use and in starts to have really bad impact on other things, my browser stops responding, the download speed plummets , windows explorer barelty creeps along - directory windows pretty well stop functioning....

Win Xp SP3, java 1.6u10. 6 chunks and 4 downloads.
When it finished downloading, the memory got reduced to about 150 MB.

I will try that when i get back from work.

Thanks.

I disabled all effects, and tried that command line. Now it uses about 490MB.
Still very high, but as soon as it won't get higher, i can live with it.

I'm downloading one file at the moment.
Have effects off, running under Win2k, Java 1.6

Process "javaw.exe" is using 45 MB of RAM.

Nothing else significant, Opera browser is using 150 MB, HCEnc (encoder) is using another 150 MB.

At one point, I noticed my javaw.exe using over 500MB. I shut down this process in the task manager. Upon restarting, javaw.exe used far less memory (around 53MB), but some of the completed downloads from my previous session remained in the download list. I remember that I had used the Cleanup/Remove completed packages command before restarting JD, but it seems that some of the previous sessions remained in memory, resulting in the 500MB usage, and a "database save error" that I noticed in the log may also be related.

I would suggest that a user look at his task manager periodically to see the memory usage, and if javaw.exe is still a running process after shutting down JD, kill the process. Now, if you have another java app running at the same time as JD, this might kill that app too. Also look at the log for database save error.
