Performance issues since upgrade to 5.2.3

We upgraded from 5.0 to 5.2.3 (5.2.3.3831) in June. Since then we've seen a dramatic performance drop with regards to the alerts and website performance. The Analysis graphs are also very slow and at times not functional at all... (at time it takes 30-60 seconds to load the list of instances when I click on one of my cluster nodes in order to drill into a specific disk, database etc.

I read through the release notes in the 5.2.4-5.2.6 release notes and I don't see any changes to correct these performance deficiencies...
Please let me know if you have any suggestions.
Thanks,
-Luke.


We are monitoring 26 servers. Number of alerts = 133810

    For those reading this, we upgraded to 5.2.7 and performance is significantly better.

    I reviewed our SQL monitor instance again and it seems like there was some improvements, however the analysis section is still slower than it was in 5.1.

    the metric selection prompts do not appear to be displaying properly. At times they are very sluggish and sometimes will not populate at all. this is with I.E. When using Chrome everythign is even slower and the metric selection boxes rarely populate correctly.

    This is particularly bad when reviewing Database metrics on a Clustered instance. for example, I perform the following...
    Click the Analysis tab, wait 2 seconds.
    Choose the Database|Total size metric.
    Choose a Cluster. Wait a second (or sometimes more).
    Select an instance name. wait 5 seconds and the database list loads. I am able to move around between various databases and performance is as expected.
    If I select another instance on the same cluster I wait 30+ seconds for the database list to load.

    The experience drawing the graphs etc seems to be faster but the prompts to get me there seem to not function as well as they used to.

    I did not have these kind of issues when using this product in the 5.0 or 5.1 versions.

    Does anyone have any ideas on places to look for configuration changes etc to make this product run faster?

    Here are the performance metrics from the diagnostics page since we upgraded to 5.2.7 - we are receiving errors from the /GlobalOverview/GlobalData check which we did not receive before.
