<p class="MsoPlainText">Hey Naresh,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The RAM you need would differ by the nature, hardware and couple other things about the nature of the machine.<o:p></o:p></p>
<p class="MsoPlainText">What you need is start from the bottom and move up.<o:p></o:p></p>
<p class="MsoPlainText">List for yourself the machine specs and your goals.<o:p></o:p></p>
<p class="MsoPlainText">It really helps to start from low ie the default 256MB ram cache and without any cache_dire and then see how it all moves on from there.<o:p></o:p></p>
<p class="MsoPlainText">For now you are getting to the 19 hours of up time and you need to overcome this so just start with a dry run of no disk cache at all and stick to squid defaults for the next 24-48 hours.<o:p></o:p></p>
<p class="MsoPlainText">Also what OS are you running?<o:p></o:p></p>
