Dan, sometimes our 8-processor AIX server slows down for no apparent reason.
May be this is the "performance degradation due to thread management issues"
you spoke of.   Is there an APAR on this problem,  or do you have more
information / solutions?

Thanks....

Subject: Re: Is ADSM/NT or ADSM/AIX a better choice?


Michael,

I have worked with all three platforms.  If you primary criteria is
performance, then you will be happiest running ADSM/AIX H50.  According to
the IBM performance reports the AIX server should perform at approximately
2x that of the NT server.  The AIX server should also scale better.  I have
a customer that is backing up over 400 good sized clients to one RS/6000
R40- 4way.  I would recommend the H50 4way, but no larger.  There is a
potential for performance degradation due to thread management issues on a
server larger that a 4 way.  You will be challenged to provide enough of a
load to outgrow the 4-way;  in fact, a 2-way may serve your needs.  The
ADSM/AIX server has been available for several years and is probably the
most solid of all the ADSM platforms.

Please feel free to contact me for additional information.
