var cmdBenchmark = &Command{
|
|
UsageLine: "benchmark -master=localhost:9333 -c=10 -n=100000",
|
|
Short: "benchmark on writing millions of files and read out",
|
|
Long: `benchmark on an empty SeaweedFS file system.
|
|
|
|
Two tests during benchmark:
|
|
1) write lots of small files to the system
|
|
2) read the files out
|
|
|
|
The file content is mostly zero, but no compression is done.
|
|
|
|
You can choose to only benchmark read or write.
|
|
During write, the list of uploaded file ids is stored in "-list" specified file.
|
|
You can also use your own list of file ids to run read test.
|
|
|
|
Write speed and read speed will be collected.
|
|
The numbers are used to get a sense of the system.
|
|
Usually your network or the hard drive is the real bottleneck.
|
|
|
|
Another thing to watch is whether the volumes are evenly distributed
|
|
to each volume server. Because the 7 more benchmark volumes are randomly distributed
|
|
to servers with free slots, it's highly possible some servers have uneven amount of
|
|
benchmark volumes. To remedy this, you can use this to grow the benchmark volumes
|
|
before starting the benchmark command:
|
|
http://localhost:9333/vol/grow?collection=benchmark&count=5
|
|
|
|
After benchmarking, you can clean up the written data by deleting the benchmark collection
|
|
http://localhost:9333/col/delete?collection=benchmark
