Re: OT: When to upgrade bandwidth?

do you have any methods of QoS on these links?

which specific applications are slow? and does slow mean they do not work or
do users complain?

What traffic is causing these 95th % spikes and for how long are they
sustained? Can you get rid of this traffic? Or police down so the other
'mission critical' traffic can utilize these spikes of bandwidth?

if you have the money to spend why not more bandwidth is never a bad thing,
but not always the correct answer either...

you say the connection is 'slow' to the Internet, is it fast when your
monitoring tools say there is no traffic on your T1 or is this a contention
ratio issue with your ISP to the "Internet"?

HTH,

thanks..
