php - What can delay "Time to First byte" by almost 2s? -


i have enabled php profiler, magento, still profiler. standard magento compiler records processing including db queries create page, receiving request.

mage-profiler

i testing php built-in server hosted locally.

the results show pretty decent server response times, on chrome developer tools time first byte higher. why this?

take note...the screenshots below of timings same request...clearly

profiler (www.mysite.com/index.php):

magento-profiler-server-response

developer tools (www.mysite.com/index.php):

ttfb-chrome-developer-tools

edit

i had written bit bigger answer realized using built-in php server. honestly, should give real webserver go. might chasing problem not exist (although 1 can argue there going on because it's not normal situation - might encountering php bug) ;)

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
