+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'.
