Sorry..Enter pressed :) continued... no, it's not the only way to check, but it depends what you want to use ceph 2014-08-26 15:22 GMT+04:00 Irek Fasikhov : > For me, the bottleneck is single-threaded operation.

Re: [ceph-users] enrich ceph test methods, what is your concern about ceph. thanks
For me, the bottleneck is single-threaded operation. The recording will have more or less solved with the inclusion of rbd cache, but there are problems with reading. But I think that these problems can be solved cache pool, but have not tested. It follows that the more threads, the greater the speed of reading and writing. But in reality it is different. The speed and number of operations, depending on many factors, such as network latency.

Re: [ceph-users] enrich ceph test methods, what is your concern about ceph. thanks
thanks Irek Fasikhov. is it the only way to test ceph-rbd? and an important aim of the test is to find where the bottleneck is. qemu/librbd/ceph. could you share your test result with me? thanks 在 2014-08-26 04:22:22，"Irek Fasikhov" 写道： Hi.

hi,all i am planning to do a test on ceph, include performance, throughput, scalability,availability. in order to get a full test result, i hope you all can give me some advice. meanwhile i can send the result to you,if you like. as for each category test( performance, throughput, scalability,availability) , do you have some some test idea and test tools? basicly i have know some tools to test throughtput,iops . but you can tell the tools you prefer and the result you expect. thanks very much ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
