How to measure insert time?
Using the kx pacakge to do a bulk insert, how do I measure the insertion time, excluding network latency?
KdbConnection.c.ks("insert", table, flip);

If it is possible you should be able to replace your "insert" with the following
"{start:.z.p;x insert y;.z.p - start}"
essentially define a start time, do your insert, and then return the difference between the start and current time.
if you also have direct access to the q session you could also try something like
t:10 `table_name insert data
in the session to return the time it takes to do 10 (or whatever number is needed) run throughs of insert.
One thing to bare in mind: the former method will return in nanosecond format, the latter in milisecond (hence why we do 10, or more if needed, iterations of it).
