You could see the 'Additional delay' under Client processing delay section for each request, under Advanced tab.
What happens if you make this delay to zero??
Does the play back show much difference in overall response time?
Generally, the time taken to load the entire page outside IBM Rational Performance Tester (RPT) cannot be mapped to the time taken to load the same page when invoked via RPT recorder. There are lot of parameters that RPT, as a load performance testing tool, accounts for (such as the traffic and connection information).
Also, RPT processes these Client side delays in parallel or sequentially depending on how the application server returns them. Sometimes if you try modifying/disabling the client processing delay value, it may also disable the immediate transaction under Rational Performance Tester. Because, practically speaking, when you disable a request, you potentially invalidate some delays because in theory the disabled request could have been the basis for a delay. Therefore, RPT automatically recalculates the delays on the page when you disable a request. That is, if a later request used the disabled one as a base, the later delay request should be adjusted.
Now, let's come to your question about why such discrepancy between the response in the browser and RPT...
Often times when you see response times that are inaccurate it is because of recording your actions too fast and so you end up with more than one page being combined together. When recording, you need to be mindful and make sure to pause between mouse clicks. Do an action and wait 5 seconds before continuing on to the next action. You also need to pay attention to where your mouse is and make sure you have no "hover gifs" that you accidentally cause to be sent to the server while recording.
To see if you have these problems you have two things you can look at.
1. Open the test and click on the name of the test under test Contents in the tree. Click Select->Request. On the right hand side you will see a table of all requests in your test. Look at the delay column and look for really large delay values. If you have these, they are usually caused by recording too quickly, and act as an "embedded" think on the page. The Client Delay is supposed to simulate how long your client took to process the data from the server before sending the next piece of data. When you record too quickly, these values can be skewed. You can also go to a specific page that is taking too long and look at those specific requests. You can use the same Select button, or you can go to the Advanced tab of each request and look at its delay.
2. If you find the delays are your problem, then you can split the page where the delays are long since this was probably supposed to be two pages. This will move that delay to be the think time of the page which would be more accurate. You can also go to Wind
Also remember that when doing recording, we will capture each connection that was used and will send out the requests on the same connection that they were sent on originally. If you had two connections sending requests at record time, we will send requests on two connections at execution time. If you see a really long client delay, then look at that request in detail to determine if it was something that was sent by a user gesture or as a result of the primary request.

The idle standby configuration enables recovery from failover to help ensure minimal impact on business operations during planned or unplanned server outages and Idle standby deployment for crash recovery.
Refer to Impl
Important: Jazz Team Server applications allow only a single server to be active at any one time to a repository; therefore the backup (or Idle) server is configured to never run asynchronous (or background) tasks. If a switch is made to the backup server, you must plan to bring the primary server back up as quickly as possible.
Index corruption can be caused by Network, database or application server issues, to name a few. Below are the steps to fix the index corruption issue on active server, using the idle standby server.
Index corrupted occurred on the Active server and you were unable to fix it by running the repotool command on it. So we can still fix the index issue by running a repotool command on the idle standby server.
Fixing the index issue on active RTC server using the Idle standby server.
Below are steps to fix the index problem, using the IDLE standby server. The standby server is on a different machine (and pointing to a different jazz_home than the active one).

There are many instances where you get reports indicating higher page response times in the IBM Rational Performance Tester (RPT) generated reports. You tend to correlate these metrics against the usual time behavior noticed when accessing the application under test outside RPT. It could be a case as well where even if you add all the page elements listed in report, the response time is much less compared to overall response time for the transaction.
The page is considered to begin when the first action (typically a request) associated with the page starts execution. If this request needs to make a connection, the page response time will include the connection time. The page ends when the last action (usually a response) of the page completes. RPT would adjust the page response time to remove the time spent in client delays. In RPT 8.2 this changed after determining it was more representative of the real-world response time to leave the client delays in the page response time. Thus, in RPT 8.2 and later, the page response time does include client delays.
However the Think Time value set in the schedule is not included in the page response times displayed in the Performance report. It should be noted that there are potential "delays" in the script that could increase page response times. Think times are associated with pages and are intended to represent human pauses during recording - these don't impact page response times. For individual page elements (requests), there may also be delays which are intended to represent client (browser) delays (processing time for example). These will be reflected in page response times
Questions could arise such as: How does RPT calculate the Page level response time as compared to Request level response time for a given page?
In case the first request used a new TCP connection, it calculates the difference between the timestamp when the connection for the first request in the page was made and the timestamp of when the last byte was received for the last request in the page. In case an existing connection was reused, the timestamp of when the first request was sent is used. All these timestamps are available in the test log if full logging is on. If a existing TCP connection is re-used, the value "Time to Connect" in the test log will be 0 .

Rational Team Concert server is expected to have a common user base management. In order to correctly perform process enforcement for Git operations by Rational Team Concert it is imperative that the identity of the Git user be known to Rational Team Concert. Therefore, the need to have a common user base across Rational Team Concert and Git server (Apache HTTP server) via a different LDAP arrangement.
We can still get the integration done using a common user name with different user base across Rational Team Concert and Git server via an different LDAP arrangement.
Example: Git is configured with Apache DS LDAP and RTC configured with different LDAP registry.
Note: Common user id used for both GIT and RTC using different registry (with different password) and provide all necessary permissions.
Below are checkpoints for verifying the integrations:
1) Verify the GIT login, just to ensure GIT login is fine
$ git remote show origin
2) Verify the GIT GIt repo configuration
Update respective "repokey" and "repourl" information
3) Verify the GIT GIt repo configuration
Update respective "pre-receive" and "post-receive" hooks information
Note: The above configuration will give a clear understanding about RTC-GIT integrations and using a common user name with different user base across Rational Team Concert and Git server via different LDAP arrangements.
