[AGENT++] SNMP Walk creates 66% CPU load

[Gangadhar Sandrani]

Hi Frank,

Thanks for the info.

The compiler switch  “_NO_LOGGING”  is already defined in
snmp++/include/snmp_pp/config_snmp_pp.h file. Please find the below code
snippet.

 // define _NO_LOGGING if you do not want any logging output
// (increases performance drastically and minimizes memory consumption)
//#ifdef __vxworks__
#define _NO_LOGGING
//#endif

 Thanks in Advance.

 Best Regards,

Gangadhar S
