hi guys, need some help, My work machine and all other work machines are really slow and it takes ages to open Spreadsheets and folders on the network, I think this is due to only being 10/100 network and also running IP phone system causing all sorts of problems, Would upgrading to a gigabit network improve things? how could i check to see if this is the fault?

Thanks

umm, I'd say unlikely; lots of sites are only 10/100 and are fine for say around 50-100 users.
Adding faster hardware may work, but you really need to find out why this is happening


we really need lots more info in order to give sensible comments:
- when did this start happening ?
- does this perfomance problem happen when people have gone home ?
- how many users do you have ?
- do they all connect back to a central switch ?
- what switch hardware do you have ?



first step is to look at the traffic logs on your switch (if any)

otherwise locate a software network sniffer that will give you the "top ten talkers".
a nice one is the free "PRTG traffic grapher"
http://www.paessler.com/prtg
...and install a sensor on your file server, and on the ports linking your switches.
I downloaded it earlier to check and it should tell you what you need to know.




re: loading files:

I'd have a look at the performance of the file server as a possibility,
there are performance indicators you can setup to check it's behaving normally.

here are some links on what to look for:

Are your devices connected to a switch or a hub, if it's a hub swap it out for a switch as this will improve things for you a lot, also make sure all devices are running in Full Duplex as well. If there are already in a switch and full duplex, get a sniffer like wireshark (which is free) this should enable you to sniff the traffic on the network to see what is talking the most.

It looks like Colbaker is far too busy in other threads to bother posting in his own :rolleyes:

But thanks for the tip on Wireshark, Syngress :cool:
had a look today, and it's great for packet capture.
(I normally used Sniffer-Pro)


I like the capture filter for picking out stuff of interest
(! arp AND ! FTP AND host 10.0.0.5)
heh, what a doddle, love it :)
