Resolved by https://github.com/php/php-src/pull/2242. This
should make get_browser() with a large browscap.ini faster by a factor of 100x or so.

I just did some quick measurements with php_browscap.ini (~8.5 MB)
looking for one of the first and one of the last entries. Results
(in seconds):

PHP-5.6: 0.01 resp. 0.62
master:  0.01 resp. 2.98

So, indeed, there is a huge performance *regression*. This doesn't
appear to be related to ZendMM, because without it I get similar
numbers.

Well, then the ticket should be re-opened. :)

Hi,

I was wrong : the performance are really bad even with last versions, so I used php_browscap
(https://github.com/browscap/browscap-php).

Thanks for reply
Oli
