I have a copy of Download Accelerator Plus 8 and install it last night just want to try it’s performance. What I can say after I try it is, wether I use it or not, the time it takes to download is same. To download 2Mb file, it took more than 10min which mean it is same if I download without using it.
As you can see from the image above, the time left is 5min but the download is only about 59% finished. So I have decided don’t want to use any download accelerator anymore.

I guess you need to learn how accelerators work in order to take advantage of them.
Yea, I think so.
But it looks like the speed is same wether I use it or not cause I use dila-up.
even u use dial-up, should be different performance… DAP is the best on my list, i experience the performance compare to any download accelerator out there… for downloading 1 file, it will try to search & download from different site mirror for faster download & prevent from broken link… try download big files, u will see the difference…
