| Probably a problem with Disk I/O. Use the Performance Monitor in
Administrative tools. I would hazard a strong look at disk
fragmentation. Purchase a Disk Defragmenting program, or do a full
backup, initialize the disk and then a full restore.
Windows NT has a bad time with fragmentation, though MS won't admit it.

| First of all, an Alpha XL 266 is a 266Mhz 21064A, not a 21164.
A Pentium Pro 200 is about twice as fast (see SPECint, SYSmarkNT, etc)
as the Alpha, so that accounts for most of the difference. The
21064A had enough trouble keepoing up with Pentiums. Get a 500Mhz
21164 box to look good against a Pentium Pro.

Defragmented with Diskeeper. No help.
.2:
Yes. I meant to say 366.
>Get a 500Mhz 21164 box to look good against a Pentium Pro.
Sounds easy... I'll keep saying that as the customer throws me and the
Alpha's out the window.
Thanks for the info. Although I was hoping for a bit more.

| Re .0, i think you may get more by posting it in the DECWET::VISUAL
(VC++) notes conference.

| Thanks... I'll try visual and when/if I find out what's happening I'll update
this note.

| Does Digital own the machine? If so, grab the V5 Beta bits and take 'em
for a spin. If not, send e-mail to me at ecg@zso.dec.com. I'll need the
complete company name, shipping address, contact name, contact phone,
contact fax, and contact internet address.

| 3187.7 | Does WNT service pack help? | WIBBIN::NOYCE | Pulling weeds, pickin' stones | Wed Mar 12 1997 16:59 | 25 |
| The fact that file I/O seems to be the problem made this note seem relevant:
<<< TALLIS::SYS2$:[NOTES$LIBRARY]FX32.NOTE;1 >>>
-< Official FX!32 Notesfile >-
================================================================================
Note 268.5 FX32 performance with file I/O 5 of 6

-< Appears to be fixed after patching >-
--------------------------------------------------------------------------------
Mystery solved, it seems. After talking with Rich Dischler
(project mgr for the AlphaStation500), he mentioned he had
heard some rumors about performance problems with Alpha/NT that
were fixed in one of the service packs. I wasn't sure it would
make a difference, but after installing them I retried several
of the benchmarks and to my surprise, the times came in at or
under the Intel times! "SI Extract Data" time, for instance,
went from over 7 minutes to 53 seconds. I am not sure if this
perf problem is specific to NT Server (which is what I was using),
or both Workstation & Server, but I would recommend installing
both service packs if anyone does see file performance problems..
