sp_sysmon diff between cache search miss and cache miss

Hi all,

I have a question about sp_sysmon output, more precisely the figures between 'task context switch due to cache search miss' and 'cache miss' in data cache management.

Let's take an example of sp_sysmon.

The task context switch due to cache search miss shows the number below

Cache Search Misses              22.6          43.3       13582       9.7 %

This number looks high and my data cache might not be well configured but if I look at the Data Cache Management section , I have

Cache Statistics Summary (All Caches)

  -------------------------------------

                                  per sec      per xact       count  % of total

                             ------------  ------------  ----------  ----------

    Cache Search Summary

      Total Cache Hits            15436.0       29495.5     9261597      99.9 %

      Total Cache Misses             22.6          43.3       13586       0.1 %

Now the total cache misses looks fairly low and my data cache seems OK for me.

Could you explain me the difference between the 9.7% on one hand and the 0.1% on the other hand?

Thanks

Simon
