This is what I've done. Since all my files are static, I've created one
sample with "retrieve" check marked. I've run it with single thread (no
load). Then I run Firebug (to get base times). Then I generated the load
(always 5 second ramp-up). Here is my data:

http://tinypic.com?ref=29veydy  http://i53.tinypic.com/29veydy.png  

So now I have a proportion in 59%. Then I generate a load 40 threads per 5
second and I get Jmeter data 38 seconds. I use 59% and get 22 seconds for
browser time. Is my calculation correct?



Also, I have a question about unrelated test results. Do you know what these
errors are? When do such errors usually occur?
