Migration Manager console takes a long time to start, from clicking the shortcut to getting to UI the delay is over a minute
The project is very big, around 300.000 objects synchronized
during startup the console does two queries:
both take around 35 seconds, bringing the total startup time to 1 minute 15 seconds
(objectClass=aelita-Amm-DomainPair) query against QMM project in ADAM using ldp.exe took the same amount of time (~30 seconds)
According to MSDN:
Going to ADAM schema in ADSIEdit, properties of Object-Class and changing Searchflags value to 9, then waiting for event in the ADAM event log saying that objectclass was indexed the query time went down to couple of seconds.
Startup time went down to 5 seconds.
Note that slow console performance could be related to resource processing and Histories container in ADAM, this article relates to start up delays only.
