Hello,

I have been asked to "try" to quantify the impact of server performance when
enabling the FT-Engine. I plan on indexing 2 columns in two different table
the columns are each defined as Varchar(255). I plan on doing an
incremental update in the evening.

What if any would be the impact of doing a FT-Search uing the FT-Index as
opposed to doing a normal query?

Thanks,
Dan

Dan,
Primarily, you will see "impact" relative to SQL Server in disk i/o, memory
and CPU usage. Although, you will need to populate your FT-enabled table
with millions of rows in order to see this impact. You should also test your
multi-million row table using T-SQL LIKE vs. SQL FTS queries using CONTAINS*
or FREETEXT* and compare both their relative performance as well as returned
results as the results will be difference depending upon what exact search
word(s) you use. For references, you should review SQL Server 2000 BOL title
"Full-text Search Recommendations" as well as
http://support.microsoft.com/default.aspx?scid=/support/sql/content/2000papers/fts_white%20paper.asp

Regards,
John Kane
