hi guys ..... first of all the nodejs integration is awesome ...
i have integrated nodejs+ privatemsg_nodejs+drupalchat(with nodejs )

my issue is when ever there is a nodejs action happeing ... the cpu spikes up too much ...
for a 2 logged in user chatting using nodejs the cpu goes up by 10% tp 20 % ...
is it normal ?
wat if there are 50 users using the chat feature ?

scalabality can be issue ?
