If you want to measure how long your storage plugin needs to do the read and write you mount the plugin using:
.PP
.PP
.nf
kdb mount file\&.ysp user/trace_point your_storage_plugin timeofday
.fi
.PP
.PP
Then you can benchmark your storage plugin in the get path:
.PP
.PP
.nf
kdb get user/benchmark
#> get     0000000356      di      0000000356      pos     pregetstorage
#> get     0000000530      di      0000000174      pos     postgetstorage
#> hello
.fi
.PP
.PP
and in the set path:
.PP
.PP
.nf
kdb set user/benchmark
#> get     0000000342      di      0000000342      pos     pregetstorage
#> get     0000000532      di      0000000190      pos     postgetstorage
#> Set null value
#> set     0000000766      di      0000000234      pos     presetstorage
#> set     0000001002      di      0000000236      pos     precommit
#> set     0000008944      di      0000007942      pos     postcommit
