Server – ERMO EnableRetrieveMultipleOptimization

The ERMO setting is commonly used to

limit the duration of certain long running

queries (specifically, to overcome issues

related to local or deep business unit

access within Microsoft Dynamics CRM

2011 security roles.

Default value is set to 0 – Automatic the

systems figures out the best setting to use.

Use in most cases – especially useful with

larger data sets in which the number of

visible records varies a lot between

different users.

Setting to 1 if a user can only see the

records he or she owns and that number of

records is relatively small (ideally less than

a few thousand)

Setting to 2 Consider using when most

users have Read access to most records

without the use of sharing, and most users

are members of a small number of teams

and have access to records in a small

number of business units.

Setting to 3 For smaller organizations, this

format of security filtering is often

sufficient and may not require as much

memory as the default ERMO setting (CRM

4 default)

AsyncSelectMaxItems evens the load of the

Asynchronous service per organization

eliminating a possible bottleneck

workload can cause bottlenecks on the

Databases - Indexes

Non-Clustered Indexes contains pointers which

reference the location of the data. You can have many

non-clustered indexes.

Clustered indexes, Sort the column

'Amount' descendent on the table itself. You can only

have one clustered index.

Customisations Layer Security - keep it simple

Use Teams to share

records, ideally Access

Teams

avoid deep BU access

levels

Avoid sharing records

with users. E.g. use teams

sharing is a last resort

@CRMUG

Customisations Layer SkipGettingRecordCountForPaging

(removes the Paging counter)

Use more plugins/Workflows then

Business Rules instead of Javascript

removing the load on the browser

Combine webresources to one

javascript file

Avoid Sub-grids on the form

iFrames
