Dept. Date: Tue, 22 Nov 1994 19:24:42 GMT Lines: 34 Hi there, We are trying to establish a controlled environment for measurement of computer resource use (CPU, disk traffic etc.). Currently we are using the ttcp program to characterise the resource demand of TCP/IP software for different parameter settings and for different implementations of TCP. We have a dedicated Ethernet and dedicated workstations connected to this net. Still, we need to find out which "housekeeping" activities that Unix itself undertakes during our measurement experiments. The following questions arise: What is Unix housekeeping? How frequent are the housekeeping operations? To which degree does Unix housekeeping influence our experiments? Which housekeeping operations cause the most disturbance? Can we control these "malicious" operations during our experiments? What is the minimum of housekeeping tasks that need to take place during measurement experiments? To which degree is the resource use caused by Unix housekeeping accounted for in the resource accounting for user processes? We hope somebody can give us some hints.... Thanks in advance.
