sst-bench: script to measure time of various data transfer methods used for SST in Percona XtraDB Cluster


 Usage: sst-bench.sh options

 --mode        script role: donor - push data to joiner, joiner - awating data from donor

 --sst-mode    sst-methods to test: xbackup, xbackup_enc, tar, rsync, rsync_improved

 --ssl         use ssl for network connections (defaul:0 <0|1>)

 --cipher      ssl cipher: DEFAULT, AES128, AES256, CHACHA20(for socat with openssl 1.1.0)

 --xb-enc-key  file with encryption key for xbackup_enc mode

 --aesni       AESNI enabled by default (defaul:1 <0|1>)


It's required to adjust environment variables in the begining of script before usage of the test.

Example:

Archiving datadir using tar and transfered it over SSL connection between donor and joiner hosts with AES128 cipher, support of AES-NI is disabled

#joiner_host> sst_bench.sh --mode=joiner --sst-mode=tar --cipher=AES128  --ssl=1 --aesni=0
