Relation Between Throughput and Response time

Throughput= The amount of data coming from the server per 
sec in bytes for the request.

Response time= The total time between client to server and 
then server to client is called Response time.
Throughput is the no:of bytes downloaded from the server during a transaction, whereas response time is the time taken for a transaction to complete. Until the total bytes gets downloaded from the server, we cannot consider the transaction is completed. So throughput should be inversely  proportional to response time. 

 Means if throughput (no. Of bytes increas) response time decrease. 

Suppose for a login transaction, if 10240 bytes gets downloaded from the server. User has to wait until all bytes gets downloaded to consider the transaction is completed. 
With 1 user load 10240 bytes may get downloaded in 2 sec
With 100 concurrent user load it may take more than 2 sec (say 60 sec) to download same 10240 * 100 bytes.

Jmeter Preprocessor to add Dynamic parameters

Image
sub: one scenario need to capture the data from previous request and pass as a parameters in jmeter Problem: but key and pair both are dynamic and very huge values. we can't handle each parameter as below Note: Here Key and values both are dynamic Solution : we need to capture all the respose data and segrigate and pass through JSR223Preprocessor. Here is the solution. Step1: Step 2: Modify the request Add JSR223Preprocessor in the request //int count=Integer.parseInt(vars.get(“paths_matchNr”)) //log.info “parameters count” + count //vars.put("JsonResponse", prev.getResponseDataAsString()); import java.util.regex.Matcher; import java.util.regex.Pattern; import java.text.*; import java.util.*; //Paths Data List result= new ArrayList(); def count = Integer.parseInt(vars.get("ALLVALUES_matchNr")); log.info("count=" + count);//83 //["#31:218","#62:1","#61:1","#63:1","#31:2...
