| Hi,
I'm transmiting the informations that Eric has asked for on either
8203.3 and 8203.4 notes.
******************************************************************************
As Eric suggested :
>> A) dbx -k /vmunix
>> p fifo_stats (before)
fifo_wbolts_tot 0
fifo_wblots_deliv 0
fifo_wbolts_force 0
fifo_rbolts_tot 216
fifo_rbolts_deliv 72
fifo_rbolts_force 41
fifo_found_newdata 0
fifo_active_fifonodes 264
>> run test
>> p fifo_stats (after)
fifo_wbolts_tot 0
fifo_wblots_deliv 0
fifo_wbolts_force 0
fifo_rbolts_tot 172226
fifo_rbolts_deliv 172062
fifo_rbolts_force 86881
fifo_found_newdata 0
fifo_active_fifonodes 245
Results of this execution :

fifo_rbolts_tot 216698
fifo_rbolts_deliv 214532
fifo_rbolts_force 279260

The complete chart follows bellow :
--------------------------------------------------------------------------------
(A) (A) (B) (B) (C) (C) (C)
before after before after before after after vfs
-------------------------------------------------------------------------------
fifo_wbolts_tot 0 0 0 0 0 0 0

fifo_wbolts_force 0 0 0 0 0 0 0
fifo_rbolts_tot 216 172226 229 40196 220 172391 216698

fifo_rbolts_force 41 86881 67 188988 37 86782 279260
fifo_found_newdata 0 0 0 0 0 0 0
fifo_active_fifonodes 264 245 264 212 264 233 818
Time MRP (MM:SS) 14:41 02:34 14:40 14:41
Time CRP (MM:SS) 08:23 00:58 08:17 00:46
----------------------------------------------------------------------------
Important : The results become much better after assigning the 0 value to the
fifo_do_adaptive variable.
Important : The results are even better when we change from named pipes to
sockets. Doing that MRP takes 1 minute and 55 seconds to run and
CRP spends 44 seconds.

| We are currently running a MANMAN/X v3.0f benchmark, and our results are
VERY similar to .0 . Note that MANMAN/X is now a CA product, and
shares the same lineage as BAAN Triton.
Yes, I have confirmed that we are using named pipes for mmx, as the
default as described in the rpc_info init file. Based on the results
from .8, we are considering enabling sockets instead to improve elapsed
time. There are no cpu or I/O bottlenecks, but currently, under the
named pipes configuration, the application appears to be the
bottleneck, using only 10-20% of available cpu (4100, 2x400MHz cpu's).
Any tuning recommendations? According to CA, sockets is supported, but
I don't believe we (Digital) have a reference site of MANMAN/X on
Digital Unix to verify.
