The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Lotus Notes Client Bandwidth over WAN
Tags: IBM, Lotus Notes, 6.5, WAN Bandwidth
Are there any benchmark figures available for the amount of bandwidth used by a Lotus Notes client using a server located at a remote site?

The clients are used for email and some small database access, and the mail is on the server, not local, and compression is not enabled.

I'm looking for an approx bandwidth requirement per client for this kind of set up.

Can anybody offer any advice or point me in the right direction?

Our business uses 350 clients connected to a single server on-site, which then replicates with a primary server at another site. However, clients still pull databases from our location downtown. We have a 10/100 network here connected through a single 1.5mb T1 connection to the remote site. Only when users are replicating to the remote site (which is a scheduled event) do we see slow down issues. As far as a per-client bandwith requirement, it would be reasonable to allow a minimum of 100k/s transfer rates for each client as you do not want them to time out or draw out your inet connection. This is assuming 100 clients are replicating at the same time (highly unlikely). This works for us :)

Thanks,

I agree in general, but you can probably get by on 50-70 kbps per client if they are not heavy users. ALso, if you stagger the replications or do not use local replication at all, you can cut that in half at least.

I hope this helps !

i think i saw the numbers in the r6 deployment redbook that i can't find at this moment. the numbers will depend on how users will be setup (work of local replica or centralized server mail) and network compression (http://www-128.ibm.com/developerworks/lotus/library/ls-NetComp/)

Ive been at IBM for 10 yrs as a network admin.... I would say that some of the above figures are fairly accurate..... I would suggest roughly 75-100k per client, and def. use comprssion on your domino servers.....This will also help in saving bandwidth and server cpu utilization since its pretty evident that not all users will be using/replicating (whether its local or server side) mail at the same EXACT time. Hope this helps.

One more note to add..... This isn't configured on the assumption that you will be using Sametime client in conjunction with your mail client....

Notes 7 and above have sametime client option built into them and the numbers I gave are able to support that feature. Of course, the EXTERNAL sametime client is not considered to be part of Lotus Notes.
