All,
I tried the AIX client out on an IBM rs6000 H80 with 2 PowerPC RS64III
processors thinking I'd see some nice results....( XXXXX)
what did i get :[5,328 keys/sec] per processor on rc5.
I compared it with an H70 with 4 PowerPC RS64II and it comes up with [934,463
keys/sec] which seems a lot better. (YYYYY)
On OGR this does not seem to happen
PowerPC RS64III : [2,562,456 nodes/sec]
PowerPC RS64II  : [1,937,939 nodes/sec]
I know the client is a beta version. but i tried with the offical one and got
the same results.

Does anybody else experience this?
Is there that much difference between the two processors?
Is it because the auto detection fails...why does it fail (too new proc?)
any remedy?

is this a know bug ?

Stan
