slow cache working…

i noticed guys that users not logged in, even if they are not logged in they are served with new created cache file. the file was 2 min previously generated on other account i have tested… so i dont understand how it seems to work. i thought when 1 guy is refreshing and slowwww making that file the other after him going to same site should be served instantly. when i turned option to treat everyone like unlogged it seemed to work fine, but on my account when i am logged in on admin, i dont have admin bar, and i am as logged out… any ideas how to make it working fine ? :]

btw i can’t see an option when entry is updated [or edited, or new comment] to clear that cache file i see only option to clear everything…

i think that even file exist for indes, for logged out user it created new one instead of serving other made for example some minutes ago… help please ??

ADDED;

i see also second possibility of generating no needed traffic by going at 404 site… maybe some sollution of http errors to avoid this no needed traffic?

i have changed caching to mod rewrite cache/.htaccess was updates automatically, i hat to manual edit .htaccess in main folder

it helped a bit its a bit faster but still i use teleport pro to generate cache files and server is busy 100%… ??

i see a lot of time when wordpress is “thinkinh” at redirection i dont know whats wrong here ;-/
