; we have changed forums implementation with following details (for reference; see PR#192):

...

The load tests were run on 4x c4.2xlarge instances for lms and 3x m4.large instances for forums.

The results of load tests below show differences between the old and new implementation. The two set of results looks quite similar except when it reaches "No. of clients = 336"; where there is huge difference between old and new percentiles as well as sudden rise in percentile for both old and new index with respect to "No. of clients = 224". For all the next tests (i.e. No. of clients = 460, No. of clients = 510, No. of clients = 578), the difference between old and new percentile is minimised and the new index results have lower percentile for most of the endpoints.

I have captured new relic charts too; permaLink_old_index with average rpm = 1.86k and permaLink_new_index with average rpm = 1.81k
