sometimes I see Hmm taking too long error then going to the link,
I remove Homepage caching and JS compression also, user/login not cache, then everything is fine,

my VPS server doesn't have meme cache You have to pay a lot to get that. so does this means that my Cache plugin cannot work without memecache.?.
thanks

@codebarre
Cache plugin does not use memcache at all.
How long it takes to create cache? (admin see it in right bottom corner).
Try to disable compressions and gzip.

Everything is Normal, it's fantastic how it's working,
I have only one question , if a client wants to edit the item, then he will not see the updated information until the cache is refreshed, how to solve this without not disabling the option. (Enable Item Page Caching)

Thanks.

You did a great work, at the Caching, well done.

Cache is refreshed after editing or publishing item
