My Windows 7 memory management is set to "Auto" so it increases the size of the pagefile if it "feels" it's needed. About "Max Time For AsyncEnterWorld" it's spamming a lot because I do a lot of side things - browsing, playing, recording video... if I just load the server without doing anything else and play on my sister's laptop on it I don't get this message at all.
It's ok dude I got used to ppl who don't believe me :D
It's not bad idea to use USB Flash Sticks :)
I think SSD could perform better although I'm not quite sure about it ("paging file" on SSD vs. "Ready Boost" on USB 2.0 vs. "Ready Boost" on USB 3.0). Anyway they are more expensive maybe it's better to just add more RAM although DDR2 for laptop (my case) is quite expensive these days because of well known reasons.
