An application developer has generated a remote procedure call (RPC) trace file for a high level
operation executed in TaskSpace that is performing poorly. A profile of the trace indicates the
following:
****** TRACE_RPC_HIST (D6 VERSION) ****
DURATION (secs): 15.781
TIME SPENT EXECUTING RPCs (secs): 13.620 (which is 86.31 percent of total time)
Threads: 2
Connections: 1
What is a likely cause of the performance problem?

A.
frequent JVM garbage collection on the application server

B.
high latency between the browser and TaskSpace

C.
an inefficient query execution plan used by the database

D.
insufficient memory on the application server
