Performance Testing Quiz - XVIII: Solutions

Yesterday's quiz was based on the basic formula:

No. of Users = (TPS/No. of Transactions)*(RT+TT+Pacing)

where 

RT: Response Time

TT: Think Time

For a quick calculation, you can bookmark these calculators:

1. TPS Calculator

2. Pacing Calculator

3. User Load Calculator

4. Think Time Calculator 

5. LG Calculator 

Solutions:

1. Based on the above-given formula:

=> 100 = (2.5/5) X (15 + 15 + Pacing)

=> 100 = 0.5 X (30 + Pacing)

=> Pacing+ 30 = 100/0.5

=> Pacing = 200 - 30

=> Pacing = 170

2. Based on the above-given formula:

=> 500 = (5.13/18) X (180 + TT + 10)

=> 500 = 0.285 X (190 + TT)

=> TT + 190 = 500/0.285

=> TT = 1754.4 - 190

=> TT = 1564.4

=> Think time per transaction = 1564.4/(No. of Transactions-1)

=> Think time per transaction = 1564.4/17

=> Think time per transaction = 92.0

3. Based on the above-given formula:

=> 80 = (TPS/5) X (50 + 10 + 20)

=> 80 = (TPS/5) X 80

=> (TPS/5) = 80/80

=> TPS = 1 X 5

=> TPS = 5

4. Based on the above- given formula and figures:

=> TPH = TPS X 3600

=> TPH = 5 X 3600

=> TPH = 18000

5. Based on the above-given formula and figures:

=> IPS = TPS / No. of Transactions

=> IPS = 5 / 5

=> IPS = 1

6. Based on the above-given formula:

=> Users = (2.6/20) X (100 + 20 + 10)

=> Users = 0.13 X 130

=> Users = 16.9 (approx 17)

7. Based on the above-given formula:

=> Users = (1.2/1) X (0.5 + 0 + 2)

=> Users = 1.2 X 2.5

=> Users = 3

8. Based on the above-given formula:

=> Users = (1.2/2) X ((0.5 + 0.5 )+ 0 + 2)

=> Users = 0.6 X (1 + 0 + 2)

=> Users = 0.6 X 3

=> Users = 1.8 (approx 2)

9. Answer: Yes

10. In case of 1 transaction, you can not provide think time. Hence answer is zero.
