The performance of Bitrix (12.0.6) decreased significantly after updating Mac OSX to Maveriks 10.9.3, what could be the reason for this?

Question

PHP

Good afternoon!
I recently updated the OSX version to 10.9.3, after which problems began with the performance of the local version of 1C Bitrix (12.0.6). Response time increased from 0.001 sec to 5-6 sec. With what this can be connected?
- Updated:
-- apache2
-- php (from 5.3 to 5.4)
The code hasn't changed. The database is used externally, I noticed that the number of mysql (read / write) operations from Mac is about 300, from windows (on another machine but to the same database) - about 1700.
Thank you!
