How can I justify the network performance between 2 end?

[miltongoh]

Hi,

As per topic, how can I justify the performance between 2 networks that causes slow network?

Like other than using PING / FILE TRANSFER?

what u trying to get? :s11:

There is this constant lag-ness between this 2 networks, just want to justify whether it is the uplink/downlink problem or whether is which ever side of the network that is congested or lag in bandwidth.

[_lucif3r_]

tracert might do the job.

Agrees, but I prefer something that gives me more concrete data.

Thanks anyway!

You nid describe abit onto your current setup.
Anyway, how did u came to the conclusion that there is connectivity problem between the 2 networks?

Current I have 2 servers located in 2 different location. Location A & Location B.

Location A connects to Location B server for the database usage. While Location A holds the web server that pulls the records from Location B.

However, on using the application at the same network as Location A, it takes hell lots of times when fetching data from Location B.

While I have tested on another line in my office to connect to the database server at Location B, the speed is still acceptable and not as lag as compared to connecting from Location A.

How do I justify that there is this latency or lagness occured between this 2 location? :)

Thanks for your recommendation. It seems to be useful. I will explore on this software.

Thanks big time!

Sounds like you have router bottleneck here. SQL traffic can generate a lot of packets, if you enforce too many layer of protection, ie stateful AV etc... your throughput will be much lower.

Noted, will try out in the situation when AV and FW is being shut off. :D

Both cant be placed on the same network?

Likely to be Web based SAP/ERP/Peoplesoft type application.
It can also be TS has alot of remote sites where DB is hosted centrally and application is run locally.
Other reasons is for security, where important like DB server are kept isolated from all traffic less from a few given source IP / ports.

Unfortunately no. :(

Check you WAN link utilization between location A and B to see if the link is congested; based on the report may be able to justify your upgrade.
