Oh, sorry again. We didn't resize the image, just "aio_discard"ed the data from the offset 1048576 to the end of the rbd image. 发件人: 许雪寒 发送时间: 2017年4月9日 16:37 收件人: dilla...@redhat.com Cc: ceph-users@lists.ceph.com 主题: 答复: [ceph-users] 答复: 答复: rbd expord-di

Re: [ceph-users] CephFS kernel driver is 10-15x slower than FUSE driver

Try running your initial test in reverse. Copy or of fuse first and then the kennel driver. I think you'll find that you are dealing with more than 1 later of caching affecting this test. Caching on the OSD and kernel caching primarily. On Sat, Apr 8, 2017, 8:04 PM Deepak Naidu wrote: > Hmm pret

I tried Fedora 25 (kernel 4.10.8-200.fc25.x86_64) with the kernel driver and it works great. Perhaps you're on to something with the kernel version. I didn't realize how far behind 16.04 was on this. I will give upgrading Ubuntu 16.04 to a newer kernel the old college try. Thanks. On Sun, Apr 9,
