Could you please give me a hint how would I prevent clearing the browser cache between the iterations?
I use TC Chromium, LR 12.53 and I found not really a good way to test with the warm cache. For the http script it seems to be much easier / work properly - the corresponding options are there available in the scenario Browser settings. For the TC script there is also an option concerning the Temporary Internet Files - I have set it to "never check for newer versions of the stored pages", but it does not change anything. The response times are same as with the cleared cache.
