No. of Worker actors created

The number of worker actors created : 50

Size of work unit of each work

Test Scenario

mix run proj1.exs 100000 200000

No. of Workers	Unit Size	CPU/Real Time (%age)
1	100000	129
2	50000	203
5	20000	347
10	10000	377
20	5000	407
30	3333	392
40	2500	411
50	2000	418
60	1666	411
70	1428	418
80	1250	394
90	1111	389
100	1000	416
200	500	417

From the data collected, we determined that CPU/real-time percentage is linearly dependent on the no. of workers. We inferred that increasing the no. of workers beyond a certain point yields no qualitative improvement on the performance for this set of input range.

Therefore, we have decided to keep the no. of workers to be 50 in our case, for this particular input.

Scenario 2

mix run proj1.exs 1200 12600000

No. of Workers	Unit Size	CPU/Real Time (%age)
10	1259880	214
20	629940	423
25	503952	518
35	359965	682
45	279973	728
60	209980	728
70	179982	714
100	125988	734
200	62994	726

As it can be seen, the CPU/real-time percentage is different and reaches close to 720%
