Tperf calculation for my system

Hi,

Good morning.

We have a 5650H system for which I want tyo understanf onm how to calculate the TPERF value.

Browsing over all the posts, I came to know that we can calculate the TPERF using the below query

When calculated, I got a value of 18k but as per my understanding having 5100M as 1.0 , I thought I would be getting some value ranging from 1-100.

Kindly do correct if there were any mistakes in the query

LOCK ROW FOR ACCESS

SEL MAX(TPERF)/1000 FROM (

SELECT

THEDATE,

THETIME,

SUM(CPUUEXEC) CPUUEXEC,

SUM(CPUUSERV) CPUUSERV,

SUM(CPUIOWAIT) CPUIOWAIT,

SUM(CPUIDLE) CPUIDLE,

(SUM(CPUUEXEC)+SUM(CPUUSERV)+SUM(CPUIOWAIT)+SUM(CPUIDLE)) TPERF

FROM DBC.RESUSAGESPMA

WHERE THEDATE = DATE

GROUP BY 1,2)DT;

regards,

Subramanian kaushik Gurumorthy

Re: Tperf calculation for my system

Kaushik,

There is a TPERF rating for every Teradata Systems. By using that TPERF rating for your system, you can able to calculate the required TPERF. Even I don't have much idea on this, but below 2 links might help you.

Thanks,

Re: Tperf calculation for my system

Teradata Tperf isn't a number that can be calculated, it's assiged to each node generation based on tests that have been executed against the node generations hardware. Adding a link that I came across today looking for the tperf numbers for older generation hardware.
