Might get you to post the actual table schema though, so we can check it. Just 
script the whole table, indexes, etc.

 

First comment is that you shouldn’t be using text at all. Apart from the fact 
that it was deprecated back in 2005, the data for that is (by default) stored 
out of row, not with the rest of the data. That’s never quick.

Message text

 

I don’t have the stats yet but some of the apps are services that run batches 
of things and have busy periods during the day where they could write maybe 
10,000 thousand rows. Possibly several times per second maybe.

Hi Tom,

 

Can you post the table schema?

 

What rate are the writes coming in at?

Subject: [OT] Sql Server writes causing contention

 

Hi folks

 

Scenario:

Multiple apps writing to a Log table in the same Sql Server database. Some apps 
hitting the table A LOT. No app reads from this table. No updates also. Just 
plain writes adding new rows.

 

Problem:

Contention causing timeout errors.

 

Can anybody explain why this could be case?

 

Cheers

Tom
