Rsync push is slower compared to pull

Source and Target remain same. The way rsync is being invoked is
different. First time, I have run rsync in pull mode, which means that
rsync daemon runs on source and target (client) pulls it. Second time,
daemon runs on target and client runs on source intern source pushing
the data. Please find the commands below for more clarity:
PULL mode:
Daemon command: "C:\Program Files\InMage Systems\FileRep\inmsync.exe"
--daemon --no-detach "--config=/cygdrive/C/Program Files/InMage
Systems/Application Data/daemon.conf" --port=874 --port=874
Client command: "c:\Program Files\InMage Systems\FileRep\inmsync.exe"
--port=874 --block-size=8192 --timeout=2400 -vvv --super -r -z -u -c -l
--safe-links -A -o -g -D -t -x --stats --progress 10.0.0.49::job_1
/cygdrive/E/H
PUSH mode:
Daemon command remains same as above. (This time it runs on target)
Client Command: "c:\Program Files\InMage Systems\FileRep\inmsync.exe"
--port=874 --block-size=8192 --timeout=2400 -vvv --super -r -z -u -c -l
--safe-links -A -o -g -D -t -x --stats --progress /cygdrive/H
10.0.1.50::job_3
In push mode, please observe that client command is trying to push data
from H:\ to e:\ drive on 10.0.1.50.

Do these identical scenarios also include changing the sender and
receiver
for both push and pull ? That would be required to dismiss the network
configuration/environment as the possible cause.
