SharePoint Stack Exchange is a question and answer site for SharePoint enthusiasts. It's 100% free, no registration required.

I have a list that includes several lookup fields. Some of these are simple lookups (only one value allowed), others are multi-lookups (the "allow multiple values" checkbox is selected).

I have noticed that these multi-lookup columns have a big impact on performance, retrieving views that include multi-lookups are much slower than views with single lookups.

Are there techniques to make these views faster? For example server side settings, indexing options, etc.?

The only option is not to show these columns in the view.

If you need to show the data and have high performance, then you might consider adding a readonly text column to show and have an event receiver populate that with the values from the multivalue lookup column.
