Hi,

After our latest vendor upgrade we have experienced a very long execution time on our CI server. After digging into it I found the following:

Symfony 2.6.5, Win 7 x64, dev mode:

Total time  755 ms
Initialization time     480 ms

composer update symfony/symfony

//...

- Removing symfony/symfony (v2.6.5)
- Installing symfony/symfony (v2.6.8)

(no other vendors were updated)

Symfony 2.6.8, Win 7 x64, dev mode:

Total time     9622 ms
Initialization time     9405 ms

• problem present on linux as well
• php error log empty
• dev log seems normal
• prod mode is unaffected

Any help would be much appreciated.
