I tried on my eMachine 355-M571G251lkk (double core CPU) with 1 G RAM, compared with Mint15 it was slightly faster but as soon as I opened more than one program, it showed obvious memory leak - the mouse cursor frozen or the drop-down menu clicked refused to show menu items apart from a grey box. Basically it is unusable so to speak. During installation, when the installation almost finished, the application frozen at 'copying installation logs'. I forced it to switch off. Is this the reason? I previously used Lubuntu without this problem. Later on I changed to Mint due to though Lubuntu a bit faster, it is apt to annoying problem like missing menu bar while Mint is more reliable and also fast enough.
