Managed server
| Posted by jamesthorpe, 06-25-2008, 07:14 PM |
| Hey guys,
I am having some problems with a server that our organisation manages, and I don't know that much about it, so I thought I would ask the experts!
The server currently has a 1mbps uplink (slow, I know). It is brand new, load is no problem.
What is the usual uplink speed of a server? How long will it take for users to download a page? How many sessions will that speed be able to support?
Please, excuse my ignorance.
If I have posted in the wrong forum, sorry in advance.
Thanks!

| it depends on the network you are currently own. Your host is the best source to get the answer from

| Cool, As a rule of thumb though... is 1mbps fast enough to run a website that will recieve upwards of 1000 visitors a day?

| The math is simple. If your connection to the internet is 1mbps then:
1.) 1 mbit = 1048576 bits
2.) You have to convert bits to bytes to understand how big a file you can transfer
3.) 1048576/8 = 131072 bytes or roughly 131KBytes
This means if your connection was working like it should, the maximum file size you could transfer in 1 second would be 131Kbytes.
So based on that you should be able to figure out how long it would take 1 user to download one page. Lets say the file its a 1 Mega Byte file, you would divide
1048576/131000 and you would get 8 seconds.
If the file is 10K lets say.. the divid 10,000/131000 and that would be .00007 seconds.
Depending on what kind of content or files your moving from the server the pipe you have may be good enough. If the files are large and you have lots of images than thats a meager connection at best. Most internet connected servers at a data center would be connected to at least at 10Mbit port that has a T3 45Mbit connection going out to the internet. I would not host a web server on a 1Mbit connection unless it was for some simple static pages with not many visitors. Have you guys considered co-location or a dedicated server?

| Awesome explaination!

| Definitely a good explaination. Remember though that on 1mbit, you should be aiming for 125KB/sec+, but if you are serving web requests there are a number of factors that will determine how fast a "page" actually gets served.
1) What is the latency or "speed", 1mbit is bandwidth. If you have poor latency transfers will appear "slowed".
2) Where is this hosted? On a xDSL line the latency will be higher and your 1mbit will likely give you 110KB/sec+, in a colo center, you should be aiming for a substantially lower latency and 125KB/sec+ as your bandwidth
3) Is the software configured correctly? Is the server hanging on unresolved DNS requests? Is your web/database server(s) optimized in terms of threading and performance?
Hope this is of use,
Adam
