Dear Mr. Dachary and all, Recently, I found your blog show the performance tests of erasure pools (http://dachary.org/?p=3042 , http://dachary.org/?p=3665). The results indicates the write throughput can be enhanced significantly using Intel xeon CPU.
I tried to create an erasure pool with isa plugin, reed_sol_van technique, and k/m=4/2 on the Intel(R) Xeon(R) CPU E3-1245 v3 @ 3.40GHz machines. However, the results of the rados benchmark showed that there was no any difference between the jerasure and isa plugins. It seems very strange. Do I need to do other configurations in addition to only setting the erasure profile? In addition, how can I know the erasure pool is accelerated by ISA plugin exactly? Is there any command I can use? Thanks, :) Derek Su. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
