I'm trying to download a previous version of JDK (1.6 update 24) from here: http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html#jdk-6u24-oth-JPR
but the download speed is very, very slow: 91-100 bytes/sec.
I'm from romania.
It might just be conditions you will occasionally experience and will have no control over.
This most recent post of yours is in July-August 2012, exactly when the 2012 Olympics are occurring in London (with all of its media data flow of its content). For all we know, there is some saturated line in between you (in Europe) and the download source (in North America) that your ISP just doesn't care to work around.
You may just need to be a bit patient and perhaps time your downloads to a different part of the day.
