Performance - steps to improve

[bgeoghegan]

What would people suggest to diagnose user reported performance issues?  I have fast typing LMI users who complain of lag times and slow screen response to their input.  Where would people look first: Internet Bandwidth, firewall limitations, LMI itself?

Based on feedback from one of my savvier users, the client settings can boost performance when set to:

Low bandwidth (see below)

Medium color depth, though on occassion HD is rendered faster.

 I've seen bandwidth used by a single LMI client reach peaks of 3-4 Mbps.

I would appreciate hearing from LogMeIn on recommended bandwith per client - active and idle.  What do LMI's own performance tests point to as bottlenecks?

@bgeoghegan  Thanks for the feedback. 

There are a great many variables to say what the average connection demands are with LMI Central clients.  Typically lower resolution systems will update faster on the screen if a user is rendering some larger graphics, however just sending type keyboard strokes should always have a delay less than 1 second. 

If this is only affecting some environments, it is most likely related to latency on that local area network.  You might consider running a few more tests with other PCs on that LAN, and make sure they are not on WiFi at the time...

Thanks Ash.  I'll add your list of issues and suggestions to the LMI user best practices document we're putting together.
