Comment 9 for bug 410841

I have tested the less memory consuming Mixx version at the weekend. First of all, the biggest memory leak is definitely fixed. After 4 hours of playing, the modified version of Mixxx 1.7.0 took about 300 MB of memory (remember that the original version takes about 1.5 GB). After 6 hours of non-stop playing, it was about 400 MB.

To summarise:
If your system has enough RAM, let’s say 1GB, you should not get problems on Linux/Ubuntu. A fresh (K)Ubuntu installation will require about 500 to 600 MB of RAM when you use Gnome or KDE as desktops. Same argumentation should be valid for WinXP. On Vista, however, you will probably need more that 1 GB of RAM. Otherwise, the swap files are used which may influence the latency.

My test environment consists of an Intel Dual Core Processor with 2 GB RAM, Kubuntu 64bit. No vinyl and MIDI interface. I used MP3 files which are mostly encoded in 192 or better qualities.

Unfortunately, Mixxx "crashed" after 6h20min. The sound suddenly became very slow. But that’s probably because of my two cheap sound cards (about 10 EUR each). Next time I try to use the Audio4DJ.
