What determins bandwith allocation to simutaneous requests?
Posted on 2008-10-27
I have 2 sites.. lets call them A and B. each fed by a T1 leased line Internet connection.. both have PIX 515 connected to telco provided routers.. only difference between the 2 PIXes ... Site A has an unrestricted license and site B has a restricted license... Site A NATs out from a pool of about 30 IPs.. Site B NATs out from 2 IPs and then switches to PAT...
The behavior I'm seeing at site A is.. all simultaneous downloads balance out, more or less. to use the full 1.5Mbit of the T1.. and general web browsing, SSH connections are largely unaffected..
At Site B on the other hand.. all simultaneous downloads balance out, more or less to use the full 1.5Mbit T1.. BUT general web browsing at this time CRAWLS at sub modem speeds, SSH connections are almost unusably slow.. yet if I start another download.. it will creep up in speed to roughly 1.5Mbit / # of downloads..
hopefully this is making sense.. My question is .. is it the PIX influencing this behavior?? the upstream router?? what?
Thanks in advance...
