As for comparing performance, that would depend on the granularity you require in your research and the hardware available, Most CPUs have cycle counter (TSC in x86, CCNT register in ARM) and if accuracy of that scale in not necessary, gettimeofday will give you granularity of microseconds. -- Mailing list guidelines and other related articles: http://lug-iitd.org/Footer
