url checker load average opensource s/w

hi

i have a few web portals  as my job profile to take care of  and i
have a request from my testing team for a s/w where i can 1) check
all links within the website  and the time taken for each link to load
, 2) and if 500 to 1000 concurrent connections are spawned the average
time for each link to load .

Is there     a opensource or paid  s/w currently available to do this .

I had tried ab testing , but it doesnt actually load the page it jsut
gives a 200 ok .

Or is there some thing i can write in perl ( if perl could you suggest
a possible module(s) )

Thanks for all the help
