Running the Performance Tests
*****************************
GDB Testsuite includes performance test cases, which are not run together
with other test cases, because performance test cases are slow and need
a quiet system. There are two ways to run the performance test cases.
The first is to do `make check-perf' in the main build directory:
make check-perf RUNTESTFLAGS="solib.exp SOLIB_COUNT=8"
The second is to cd to the testsuite directory and invoke the DejaGnu
`runtest' command directly.
cd testsuite
make site.exp
runtest GDB_PERFTEST_MODE=both GDB_PERFTEST_TIMEOUT=4000 --directory=gdb.perf solib.exp SOLIB_COUNT=8
Only "compile", "run" and "both" are valid to GDB_PERFTEST_MODE. They
stand for "compile tests only", "run tests only", and "compile and run
tests" respectively. "both" is the default. GDB_PERFTEST_TIMEOUT
specify the timeout, which is 3000 in default. The result of
performance test is appended in `testsuite/perftest.log'.
