[sheepdog-users] Concern about sheepdog performance

[Valerio Pachera]

3 nodes active.

---
Without any cache nor journal, writing 512M
  5.9M/s

These are qemu/kvm options:
  kvm -drive file=sheepdog:test,media=disk,if=scsi,cache=none \
  -cdrom /root/vm/iso/systemrescuecd-x86-3.1.1.iso \
  -boot order=d -k it -vnc :1 -m 512 -daemonize
---

---
With cache and journal enabled on all 3 nodes, writing 512M
  9,5M/s

sheepdog options
  sheep -j dir=/mnt/sdb1/sdj,size=512 -w object:size=20000 /mnt/sheepdog/

qemu/kvm options
  kvm -drive file=sheepdog:test,cache=writethrough \
  -cdrom /root/vm/iso/systemrescuecd-x86-3.1.1.iso \
  -boot order=d -k it -vnc :1 -m 512 -daemonize

0.5.5_4_ga88835e

Note: there has to be something wrong with this sheepdog version
because I have the sheep process using 93% of cpu on the node that is
running the guest.
