Hi GregorK.

I only had access to my devel box now....

Well, I did the change and things started to get better when I put the buffer size to be 63 * 1024 * 100 !!

But even with this buffer, I still saw more disk activity than it used to have with 2.6.

Also, phex rss was more than 148M for just three download files!

fxjr 26431 16.9 29.3 354796 148580 pts/8 Sl+ 11:19 0:24 java -jar phex.jar

I reverted to 63 * 1024. And now phex is using less memory, downloading the same three files:

fxjr 27105 7.1 14.2 315084 72272 pts/8 Sl+ 11:23 0:25 java -jar phex.jar

Do you have any other idea I could try out?

I was wondering if this too much disk activity could be caused by excessive flush() calls?

Did 2.6 also use java.nio?

Thanks in advance.
