when i tail -f my log:

i find this:

“Completed in 0.00233 (428 reqs/sec) | Rendering: 0.00005 (2%) | DB:  
0.00118 (50%)”

i am sure, this request didn’t access DB. but why here DB is (50%)

it’s log wrong or my fault?

regards

Hi, Joe,

may I ask why you are that sure that your DB isn’t hit? Have you  
doublechecked that if it is a page that is served from cache the  
controller  
action knows this and really bypasses the DB? Are you sure, that  
sessions  
are handled by the filesystem (the default) or may they are the reason  
for  
DB requests? What happens if you shut down the DB for this request?

Best Regards  
Jan P.
