Hi,
i was asked from jdcynical about the performance of the bulldozer cpu under proxmox.

I have made only short test - the best to compare the cpu-speed was an openvz-container (running on a ssd), which import an huge sql-file (bacula database) into a postgresql database.

This takes round 2:50 hour on an AMD Athlon(tm) II X4 620 Processor (2.6GHz).

The same job (connect the ssd to my fx-6100-host) and use the same openVZ-VM takes 10 minutes longer on the FX6100.
I had hope that the import goes a lot faster but...

I guess it's depends on the compiler-flags (and compiler-version) but at this time it's makes no sense for me to use an FX in production with pve.

Let me add to this:

I compared a Phenom II 1055T vs Xeon E3-1235. This is not a real comparison by all means but I was interssted in comparing a true 6 core vs a 4 core+HT:

PVE 1.9
pveperf 1055T:
CPU BOGOMIPS: 38528.10
REGEX/SECOND: 1088606
HD SIZE: 29.53 GB (/dev/mapper/pve-root)
BUFFERED READS: 187.34 MB/sec
AVERAGE SEEK TIME: 7.33 ms
FSYNCS/SECOND: 4253.55
DNS EXT: 1089.97 ms
DNS INT: 1301.56 ms (local)

PVE 2.0
pveperf E3-1235:
CPU BOGOMIPS: 51077.45
REGEX/SECOND: 1440137
HD SIZE: 94.49 GB (/dev/mapper/pve-root)
BUFFERED READS: 152.53 MB/sec
AVERAGE SEEK TIME: 11.29 ms
FSYNCS/SECOND: 2985.98
DNS EXT: 62.53 ms
DNS INT: 0.67 ms


BUT the biggest difference and what made me change all my servers to Intel was the power consumption:

AMD Phenom II 1055T = 170 Watt
Intel Xeon E3-1235 = 112 Watt

With the Intel CPU Server I have reduced my over all power usage by almost 40% !! This is huge!!


I switched 2 AMD Phenom 1055T Server to 2 Intel Xeon E3-1230/1235 Server

Just wanted to share....

Thank you udo and BitRausch for posting this info, this helps a lot.

This backs up what I have been able to find elsewhere, that for the long term, it's better to go with Intel. The power savings alone make it the smarter path to take.

Thanks for the info!

After reading reviews of Bulldozer, which I was waiting for, I decided to go with a Xeon W3680.
Tripple channel memory so I can easily do 24GB ECC was also a big selling point.

After seeing what Udo reports I am glad I decided to stay away from bulldozer.
I hope AMD's next CPU performs, I am tired of paying megabucks to Intel.

Hi,
i would'nt say that the FX6100 is bad. But the full affort you get only with compiled code for this cpu (should bring an huge effort).
So it's hopefully an question of time when the the build-chain full support this cpu-architecture. I will stay with amd-cpus (intel is too big).

Hi Udo,

out off curiosity what cpu/board combination are you using? I used to run my AMD Phenom II x6 1055T with an ASUS M4A89TD Pro/USB 3 before I switched.

Cheers,
B.

PS: Just to give a more detailed overview:
My current Server Setup:
Server 1:
X9SCM-F
16 GB ECC RAM
Xeon E3-1230
Highpoint RocketRaid 3510 (4 x 500 GB RAID10)

Server 2:
MSI Z68A-G43 (G3)
Xeon E3-1235
16 GB RAM
Dell Perc 5/i (4 x 500GB RAID10) (Pinmod was required)

Unfortunatly Adaptec 5405 does not work with EFI Boards - just a side note.

Hi,
different boards:
ASUS SABERTOOTH 990FX (with FX-6100 and Phenom 945)
ASUS M4A78T-E (first with Phenom 965 and now 620)
ASUS Crosshair IV Formula (with 965)

All with ECC-Ram, HW-Raid, 24/7-Disks.

I use also some Serverboards from Supermicro (with Opteron 4170 HE and 4*Opteron 6136) but since that, i'm not a real SuperMicro-Fan.
