Aerospike server got very high CPU usage when using with the php-client

[rbotzer]

Hi @Vincent_Lee. I started answering this issue on a different discussion post:

Php-fpm creating too many connections

We got the same issue for php client. In our situation, we have 5 aerospike servers and 10 php servers. On each php server, we have 500~1000 php-fpm processes. After deployed on php server with php-client-3.4.3, the aerospike servers got very high CPU usages (1200% above on 24 cores machine), even there are very few active write requests. we have enabled the persistent connection flag.

Should we continue there?
