Hi there! Recently I've noticed that I have lots of blocks missing with my delegate...  

What's the deal? What do I need for an optimal performance? 
Is it my network latency or CPU or what? Anybody knows the reason for such a misfortune?
Where are you running your server? Home or VPS? OS? Specs? Bandwidth?
Was running at home, in my office and used Amazon VPS (windows os actually). I'm still missing blocks more or less.
Decent CPUs, at least 100Mbit networks and such. What beast I need to have 100%... Ubuntu or such is better perhaps?
