One of our customer has a 35 Gb database with average active connections count about 70-80. Some tables in database have more than 10M records per table.

Now they have bought new server: 4 * 6 Core = 24 Cores CPU, 48 Gb RAM, 2 RAID controllers 256 Mb cache, with 8 SAS 15K HDD on each.

64bit OS.

I'm wondering, what would be a fastest configuration:

1) FB 2.5 SuperServer with huge buffer 8192 * 3500000 pages = 29 Gb

or

2) FB 2.5 Classic with small buffer of 1000 pages.

Maybe some one has tested such case before and will save me days of work :)

Thanks in advance.
