[OSDL][BENCHMARK] DBT2 results question

[Cliff White]

As Andrew Morton requested, we have rerun the OSDL Database Test 2 on cached
and non-cached versions comparing 2.4.21-pre3 and 2.5.49 and this time
we have vmstat data. 
Actually, we have a _ton of data, which is why i'm posting this.
What data in particular are you kernel coders looking for?

 We could graph each statistic for each set of runs for a side by
side comparison 2.4 versus 2.5.

We can also post the raw data, but 40 runs is a bit much to post on a mailing
 list. 

What would you find most useful?

 We will get the runs Andrew requested on 2.5.58 when we can get past the
I/O bug Dave Olien reported last week.

Didn't you have a standardised set of number for the dbt1 runs?  They
were pretty good if I recall correctly.

It is very hard to find dbt1 results at osdl.org.  I normally have to
grep the lse-tech archives to find anything at all.

Ah yes.

That seems a reasonable summary.

That isn't fixed yet, and there's no workaround, alas.
