| Michal Karm Babacek | 2013-12-02 13:01:29 UTC | Doc Text | Cause: Httpd shared mem operations on workers->nodes table slow down the balancer. Consequence: Performance of the httpd load balancer goes down with the rising number of registered contexts. Workaround (if any): If you experience performance problems, try to lower the number of registered contexts. Solution: Solution is being engineered along the lines of utilizing httpd local mem rather than the shared one. Preliminary results look good and a patch will be delivered. | |

Workaround (if any): If you experience performance problems, try to lower the number of registered contexts. Solution: Solution is being engineered along the lines of utilizing httpd local mem rather than the shared one. Preliminary results look good and a patch will be delivered. | A performance issue has been identified on the Apache HTTP Server with mod_cluster configured as a load balancer. httpd shared memory operations on the `workers->nodes` table negatively affects the performance of the load balancer. As a result, performance of the httpd load balancer decreases as the number of registered contexts increases. To workaround this issue, attempt to lower the number of registered contexts. A solution is being engineered that modifies the httpd to utilize local memory rather than shared memory. A fix is expected in a future release. |
