Currently, I'm just checking the performance visually.
- on laptops, we can feel the speed directly: my favorite is installing
ubuntu or debian by alternate installers
- live migration with heavy work load
Now that I've got the overall design, I want to measure the performance by numbers.
About performance under Kemari: we(oss.ntt.co.jp staffs: me and Fernando) are
now concentrating on improving the basic live-migration infrastructures and
they(lab.ntt.co.jp staffs) are working hard for building Kemari itself.
- We are also interested in using live-migration with HA software and this needs
light, stable live-migration: same as Kemari!
So measuring Kemari's performance with our patch-set will need some more time,
** How about Tamura-san? **
So at this stage, I'll show you performance improvement(I hope to improve) by
another test cases.
If possible next week!
Thanks,
Takuya
