Blackberry ENTERPRISE SERVER FOR IBM LOTUS DOMINO - - PERFORMANCE BENCHMARKING GUIDE Manual page 59

Value
Increase in average disk transfers/sec for 2000 user accounts
with wireless message reconciliation enabled from baseline =
0.33 times increase from the baseline value.
Network bytes each second increase with 2000 BlackBerry user
accounts enabled for the BlackBerry Synchronization Service =
1.36 Mbps
Sample calculations
w = disk transfers/sec, Test#13:2000 BlackBerry user accounts with
wireless message reconciliation enabled = 146.58
x = disk transfers/sec, Test#1, Baseline = 110.18
y = increase in average disk transfers/sec
Equation:
⎛ ⎞
( w x )

y
⎝ x ⎠

⎜
y
⎝ 110 . 18
Therefore, there was an increase of 0.33 times in average disk transfers/sec
from the baseline value.
x =(Network Mbps, Test#17:2000 BlackBerry user accounts and BlackBerry
Synchronization Service enabled) = 6.39
y = (Network Mbps, Test#5: 2000 BlackBerry user accounts and BlackBerry
Synchronization Service turned off) = 5.03
z = increase in network use
Equation:
z x y
z . 6 39 . 5 03
z . 1 36
Therefore, the increase in network use was 1.36 Mbps.
