Hi Jeff,
Not sure if I understand your comments fully. But eere is what I was trying to
say:
Thread Group
Loop Controller (loop count =100)
CSV Data Set Config (file1.csv, 100 users)
Loop Controller (loop count =500)
CSV Data Set Config (file2.csv, 500 users)
HTTP Request
With this, each and every user in file1.csv will go thru all 500 users in
file2.csv. I'm not able to find any collision here.
Regards,
Tien

in a Thread Group
That is a more elegant solution, but does not protect you from collisions.
That is, Thread N is going to use User A (from file1.csv) while Thread M is
also using User A userid/password. Especially with a
1:1 mapping of threads:set of user/password combinations you're likely to have
a lot of collisions.
