Description (last modified by )
gperftools provide CPU and HEAP use/check profilers. It would be good to make them optionally active in rasserver.
To turn on use cmake option -DENABLE_PROFILING=ON
This will link in the tcmalloc and profiler libs, and activate code in source:servercomm/servercomm2.cc that on SELECT / INSERT / UPDATE queries produces the following files (XXXXXX is a random string):
- /tmp/rasdaman_query_select.XXXXXX.pprof
- /tmp/rasdaman_query_select.XXXXXX.pprof.000n.heap
- /tmp/rasdaman_query_insert.XXXXXX.pprof
- /tmp/rasdaman_query_insert.XXXXXX.pprof.000n.heap
- /tmp/rasdaman_query_update.XXXXXX.pprof
- /tmp/rasdaman_query_update.XXXXXX.pprof.000n.heap
.pprof files are CPU profiling results, and .heap are the HEAP memory profiling results. These files can be analyzed with pprof, e.g:
pprof --gv $RMANHOME/bin/rasserver /tmp/rasdaman_query_select.XXXXXX.0022.heap
