Hi,
I am working on a project for improving performance, for this I am using wireshare to observe time taken by response to come back for a particular request.
for some request's , I get server acknowledgment to that request and then later i get response for that request ( say it is case 1) , but for other request ( different request url ) I get server's acknowledgment and response in the same frame ( say it is case 2).
# Case 1
I am copying wireshark frames in this case.
Request sent
"788","83.609659","192.168.130.73","192.168.133.101","HTTP","POST

Server's acknowledgement to my request

This is acknowledgement to the segment in frame in :788
Response to my request

This frame shows that it is Server's acknowledgement to my request as well as it contains response, so i am assuming that it is
response.
"266","20.899251","192.168.133.101","192.168.130.73","HTTP","HTTP/1.1 200 OK (text/html)"
This is acknowledgement to the segment in frame in :265
<script>parent.p([["TQ",1,0,"TQAUDUSD",{"V":"AUD/USD~TRD2cbe1d01ed11bd5263b743ea9d7~USD~4~2~0.0~0.0~0.0~0.0~0.0~0.0~0~20080820~10000~1.0$T1 #0.6875#0.6850#2.5E7#3.0E7#A#0#0#$T2#0.6874#0.6851#5.0E7#6.0E7#A#0#0#$T3#0.6873#0.6852#7.5E7#9.0E7#A
So my doubt is why there is a difference between these two cases ? Actually my concern is that in case#1 , I am getting response after around 400ms but in case#2 that is only 100 ms.I want to modify my case#1 to reduce this delay.
I can think of following possible
differences:
1. The size of the request is higher in case#1 as compared to case#2.
2. response is http/xml in cases#1
3. content-type is application/x-www-form-urlencoded in Case#1.
I will appreciate any help or suggestiong in this regard.
Thanks in advance.
