Morning Vineet,

Just FYI - Pay Close on LinkQA4 takes 15 minutes. Since you are using Timesheet, and you have over 10 years of data, your server needs to be built to handle the volume.

Please make sure GFI perform database maintenance. Here are some notes from what I observed:

  1. Indexing issues on the database
  2. Database is configured on the same server as Web server. This is not recommended if you are enabling audit and if the database is bigger than 20GB. See Microsoft Best practices. Configure segmenting the data files.

Regards
Sanjay

I was informed that before upgrading, the client had the WEB Server and Databases Server on separate machines. Vineet failed to include this parameter when comparing the speed between the OLD system and the New Version.

Furthermore, Databases Maintenance is not included in the LinkSOFT Support. This is a Microsoft DB task and should be managed by the client. However, we have provided some tools to assist with this. See process SYS008.

Below are the actual Execution times from the environment we have. The time provided in the case header is misleading as it was based on fragmented and poorly maintained database.

We will see what else we can do to speed this up in the next release.
