hi dietmar+tom,

just testing your latest kernel and noticed that pveperf is showing different numbers:

pveperf
Code: 
CPU BOGOMIPS:      42139.81
REGEX/SECOND:      1204265
HD SIZE:           39.37 GB (/dev/mapper/pve-root)
BUFFERED READS:    234.62 MB/sec
AVERAGE SEEK TIME: 14.22 ms
FSYNCS/SECOND:     98.84
DNS EXT:           1094.27 ms
DNS INT:           1.10 ms (fritz.box)

pveversion
Code: 
pve-manager: 1.6-4 (pve-manager/1.6/5229)
running kernel: 2.6.35-1-pve
proxmox-ve-2.6.35: 1.6-2
pve-kernel-2.6.32-3-pve: 2.6.32-14
pve-kernel-2.6.35-1-pve: 2.6.35-2
qemu-server: 1.1-19
pve-firmware: 1.0-9
libpve-storage-perl: 1.0-14
vncterm: 0.9-2
vzctl: 3.0.24-1pve4
vzdump: 1.2-8
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.12.5-2
ksm-control-daemon: 1.0-4

Usually FSYNCS/SECOND is above 3K on my system and BUFFERED READS above 260.

System Specs:
AMD 1055T
Adaptec 5405 writeback enabled
4 x SATA 500GB in RAID 10
8 GB RAM
NO VM's running.

I would love to give you comparison numbers but not sure how to revert back the complete changes in order to do that.

Kind regards

thanks for reporting!
 
Thx Dietmar,

here the results after applying the new kernel:

pveversion
Code: 
pve-manager: 1.6-4 (pve-manager/1.6/5229)
running kernel: 2.6.35-1-pve
proxmox-ve-2.6.35: 1.6-3
pve-kernel-2.6.32-4-pve: 2.6.32-21
pve-kernel-2.6.35-1-pve: 2.6.35-3
qemu-server: 1.1-19
pve-firmware: 1.0-9
libpve-storage-perl: 1.0-14
vncterm: 0.9-2
vzctl: 3.0.24-1pve4
vzdump: 1.2-8
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.12.5-2
ksm-control-daemon: 1.0-4

pveperf:
Code: 
CPU BOGOMIPS:      42141.55
REGEX/SECOND:      1191201
HD SIZE:           39.37 GB (/dev/mapper/pve-root)
BUFFERED READS:    266.30 MB/sec
AVERAGE SEEK TIME: 12.08 ms
FSYNCS/SECOND:     1593.75
DNS EXT:           1130.10 ms
DNS INT:           1.11 ms (fritz.box)

FSYNCS/SECOND is still lower then I remember...but way better the the first version.
(I repeated the pveperf command a couple of times)

Kind regards,

Both servers have identical hardware (HP DL360 G6).
 
Hi l.mirzwa,

try the latest kernel (kernel-2.6.35-3) on your first server. See also the post from dietmar in this thread. That should improve FSYNCS on your first server.

kind regards
