For years we blocked Baiduspider due to the fact their bots do not obey the robots.txt directive and can really hurt site performance when they unleash 100 bots on the site each pulling pages many times per second.
Last year, I unblocked Baiduspider's IP addresses, and now the problem is back.

papi_start
PAPI_start(3) PAPI PAPI_start(3)NAME
PAPI_start -
Start counting hardware events in an event set.
SYNOPSIS Detailed Description
C Interface:
#include <papi.h>
int PAPI_start( int EventSet );
Parameters:
EventSet -- an integer handle for a PAPI event set as created by PAPI_create_eventset
Return values:
PAPI_OK
PAPI_EINVAL -- One or more of the arguments is invalid.
PAPI_ESYS -- A system or C library call failed inside PAPI, see the errno variable.
PAPI_ENOEVST -- The EventSet specified does not exist.
PAPI_EISRUN -- The EventSet is currently counting events.
PAPI_ECNFLCT -- The underlying counter hardware can not count this event and other events in the EventSet simultaneously.
PAPI_ENOEVNT -- The PAPI preset is not available on the underlying hardware.
PAPI_start starts counting all of the hardware events contained in the previously defined EventSet. All counters are implicitly set to zero
before counting. Assumes an initialized PAPI library and a properly added event set.
Example:
* int EventSet = PAPI_NULL;
* long long values[2];
* int ret;
*
* ret = PAPI_create_eventset(&EventSet);
* if (ret != PAPI_OK) handle_error(ret);
*
* // Add Total Instructions Executed to our EventSet
* ret = PAPI_add_event(EventSet, PAPI_TOT_INS);
* if (ret != PAPI_OK) handle_error(ret);
*
* // Start counting
* ret = PAPI_start(EventSet);
* if (ret != PAPI_OK) handle_error(ret);
* poorly_tuned_function();
* ret = PAPI_stop(EventSet, values);
* if (ret != PAPI_OK) handle_error(ret);
* printf("%lld
",values[0]);
*
