Re: Data compression

["Patrick Trapp" <ptrapp@xxxxxxxxxxxx>]

There was some documentation on Lotus' site regarding compression, 
including the CPU utilization and compression rates.  As I recall, the 
utilization wasn't terribly high, but there was some difference.  Maybe 
you can still locate that article.  There might be some links to hard data 
you can base a decision on.

Personally, I have it enabled on my server, but not on most of my clients 
yet.  There's always something else...

Data compression






   I'm researching ways to improve our WAN performance besides the obvious
   need to get faster WAN links or the alternatives. Domino is a major
   consumer, with server to server mail transfer and replication, etc.

   If I enable data compression (availabe in R6) on a Domino port, this 
might
   help, but I was wondering if there is a tradeoff in CPU utilization. 
Does
   anyone know how this will impact the system? Mainly, does the CPU do 
the
   compression, or does the network adapter IOP handle the work?

   Any other experiences with the data compression? Data encryption poses 
the
   same question. I'm not interested in the encryption right now, but it
   might be good to know.

   Domino 6.5.4 FP2 on i5/520 V5R3, using #2849 10/100 Ethernet IOA, not 
the
   built in 520's  Ethernet, if it matters.
