apache too slow! high load

[just_hoster]

i've just installed 1.0.3 version. (everything default)

i've hosted 5 website and my server is dead..

can someone help how to speed up apache? it needs 6-10 sec to open webpage.... but if it opens the page, then works fine... too much time to open page...

i searched forum and found that fastcgi can speed up apache. its because of fcgid? fast cgi may fix it? or what else ?

sry for my english

thanks
