Difference in "cumulative time" in gprof's report and "TIME" in top output

[Tulsi Ram Mayala]

address@hidden strongmail-server]$ time ./system/bin/strongmail-server -i ./ -p 9010

 

real    9m59.540s

user    5m37.470s

sys     0m2.330s

address@hidden strongmail-server]$

 

 

address@hidden strongmail-server]$ gprof -q ./system/bin/strongmail-server | more

                     Call graph (explanation follows)

 

 

granularity: each sample hit covers 4 byte(s) for 0.03% of 36.18 seconds

 

index % time    self  children    called     name

                                                 <spontaneous>

[1]     92.7    0.00   33.53                 main [1]

 

 

Why does the “time” says 5mins and 37 secs whereas the “gprof” says only 36.18 secs? Does gprof exclude anything?

 

Strongmail-server exited with exit(0)

 

Also, we are using memcpy in our code. The “gprof –qz” doesn’t list it anywhere in the callgraph.

 

We are using “GNU gprof 2.14.90.0.4”
