Zend 2 Application - Issue with concurrent user access

[sreejith_y]

Hi,

While trying to do performance testing, the zend 2 web application ( back end servers: aws core 32 instances with ELB), the application works for 1500 concurrent users with 3 second interval.

But when tried with 2000 users, many requests failed. Is this an issue with the Framework

Can anyone help? can anyone suggest the apache settings for these many concurrent users

This seems to be a typical scalability issue.
Unlikely a problem with the framework: you are just reaching the limit of active users for the deployment configuration you have: you should scale it up.

Scaling is not linear: the more users, the more memory/cpu/io is going on, and if you reach the cap for any of those on any of the machines, it chokes and gets to a grinding halt (typically dropping connections or being very very slow).
