If you want to measure how long your storage plugin needs to do the read and write you mount the plugin using: 
.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
.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
.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
