In December 2015, Bitrix Inc. joined forces with Selectel and ITSumma to perform load testing of the latest version of Bitrix24 to assess system performance in a large scale business environment with a substantial number of employees and high load.
Load testing was carried out for full 24 hours on a deployed portal populated with a large amount of test data. During that period, the portal had been continuously engaged with incoming data imitating the behavior of a set of real human visitors. The virtual users were tasked to do many typical operations like logging on and off; posting to and commenting in Activity Stream; using tasks and documents; adding records to CRM; sending instant messages and performing other actions a common employee would do. Each of the virtual users had been assigned a predefined role consisting of many operations carried out in an infinite loop, with a little delay between iterations.
Therefore, the test was suited to model the real world scenario when all the employees are enrolled in the portal database and a good deal of them are using the portal throughout the day performing a number of typical actions.

Test environment:
The out-of-the-box Bitrix24 portal (BizPace Enterprise edition) installed on a single commonly used server with test data including 15 683 employees is capable of serving 5 000 employees simultaneously. Within 24 hours, this number of employees:
Maximum response time never exceeded 1,065 sec.
The out-of-the-box Bitrix24 portal (BizPace Enterprise edition) installed on a cluster of two commonly used servers with test data including 15 683 employees is capable of serving 7 500 employees simultaneously (+50%). Within 24 hours, this number of employees:
Maximum response time never exceeded 1.224 sec.
The out-of-the-box Bitrix24 portal installed on a cluster of three commonly used servers with test data including 15 683 employees is capable of serving 9 500 employees simultaneously (+90%). Within 24 hours, this number of employees:
Maximum response time never exceeded 0.949 sec!
Depending on expected load and number of daily users accessing Bitrix24, your servers should meet the following minimum hardware requirements
