 Hi @ayeshrajans !

 Thanx for review. According to your test for old version php (before 7.0)
 using constant decrease time almost for 50%. It's good indicator and imho
 shoud be merged to develop branch because still many WP sites running on
 old php versions.

 I made this fix because loading translations take most time of request
 handling after installing some extensions.

 I looked for MO loader but can't find any other obvious way to increase
 translation loading performance.

 Seems that it's requires to use some cache to not parse all mo files for
 every requests (that makes every 30 sec when admin page is opened in
 browser).
