My vps drops down if 200+ online members

[محروم.كوم]

First, I am sorry for my bad english

I don't know if the problem from vb4 or from my host

I have a vps from 1and1.com



-storage 20gb - guaranteed ram 512 - burstable ram(up to) 2gb - 100 MBit Connection - Traffic 1000gb


php 5.2.14 installed - apache 2.2.3 - post_max_size 8bm -upload_max_filesize 2mb -memory_limit128m -mysql 5.0.45


I have a page on facebook with 230000 fans, when I share a link on it, more than 300 users come to my site, it starts to become slow and then all the server stops

please some one help me to solve this problem, it's my first time to use vbulletin, is this problem from vb or my server is not good enough for the vb4
