The ceph_erasure_code_benchmark tool and bench.sh scripts use small default buffer sizes, and also contain comments that suggest running the tool with a buffer size that is too small. It can be observed from flame graphs captured while using the tool that a majority of CPU time is spent ...
Ceph is a distributed object, block, and file storage platform - test/erasure-code: increase ceph_erasure_code_benchmark default buffe… · ceph/ceph@a09fd42
Some parts of erasure coding such as the plugins are stand alone bits of code which can be tested with unit tests. There are already some unit tests and performance benchmark tools for erasure coding, we will look to extend these to get further coverage of code that can be run stand alon...
纠删码是一种冗余编码技术,可以将原始数据切分为多个数据片和附加的冗余校验片,并将它们分散存储在不同的设备上。 具体来说,Ceph使用Erasure Code来实现纠删码。Erasure Code采用一种复杂的数学算法,将原始数据切分为多个数据片和附加的冗余校验片,并计算出额外的冗余校验信息,然后将这些片段分散存储在不同的OSD(对...

Difficult to benchmark: Most benchmarks that users run to measure performance will show terrible performance with cache tiering, in part because very few of them skew requests toward a small set of objects, it can take a long time for the cache to “warm up,” and because the warm-up ...
