Have your deployments to Sitecore 6.6 installations been taking a very long time? Do your build logs show 3-4 seconds for every template item that is deployed? Are you seeing the following warning in Sitecore logs?
All caches have been cleared. This can decrease performance considerably.
If so, you are probably running on an older version of TDS. I recently ran into this problem with our TeamCity installation that was using TDS 220.127.116.11 to execute deployments. Simple deployments were taking over 30 minutes, sometimes up to a full hour. We brought that down to 5 minutes or less by simply upgrading to the latest version of TDS.
In the release notes for TDS, you’ll find the following entry for version 18.104.22.168:
Team Development for Sitecore 22.214.171.124
April 15, 2013
- Significant performance enhancements with Sitecore 6.6 deployments
The word ‘Significant’ is not lying. If you are on any version from earlier than 126.96.36.199, upgrade now to ensure your Sitecore 6.6 deployments operate efficiently! Also, note that 188.8.131.52 now introduces full compatibility with Sitecore 7, as highlighted in their release notes:
Team Development for Sitecore 184.108.40.206
June 6, 2013
- Full compatibility with Sitecore 7
- Allow TDS builds to run with a blank deploy folder location
- Fixed a problem where new version dialog box is too small
- Fixed build fails to get key problem that occurred when app pool was not recycled
