<p class="MsoNormal"><span lang="EN-GB">But after 13 days it arrives at the 5<sup>th</sup> level where before I kill the process it seed just 900MB on that level.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">This is my script<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">I know that in the documentation say that –n should be less or max the number of cpu in the server but is really slow if I put 2, so I tried with 100 and after 13 days that was the result so now I’m trying 400<o:p></o:p></span></p>
