Hi,

I run a typo3 on php5.3.10, freebsd.82-amd64 and nginx 1.1.x (no apache).

Sometimes, pages are very slow to load.
I've setup the slow-log (10s threshold) and I get this sometimes:

cript_filename = /home/USER/FTPROOT/htdocs/index.php
[0x0000000806f8c248] get() /home/USER/FTPROOT/typo3_src-4.6.3/t3lib/cache/backend/class.t3lib_cache_backend_memcachedbackend.php:335

Can someone explain what this means and how I find out what is actually slowing the request down?

I tried ktracing the requests, but this was not really successful - and the server is busy now, so ktracing is just generating lots of noise which I can hardly wade through...



Thanks in advance.

You got here functions that ran more than 10s as you set it.

May be it's not php's slow. Check I/O wait, php accelerator, mysql/whatever
database.
And what is config of your hardware?
