I have this code for FABUsersView.cs that makes it faster:
using System;
using System.Collections;
using System.Data;
using System.Web.UI;
using System.Web.Security;
using Microsoft.SharePoint;
using System.Collections.Generic;

namespace Visigo.Sharepoint.FormsBasedAuthentication

    /// Specific data of a user in SharePoint
    /// </summary>
    class SPUserData
        public string title { get; set; }
        public DateTime? modified { get; set; }
        public DateTime? created { get; set; }

    /// <summary>
    /// Data source for the User Management user display view. Gets all FBA users and adds basic membership info 
    /// </summary>
    class FBAUsersView : DataSourceView
        private FBADataSource _owner;

        public FBAUsersView(FBADataSource owner, string viewName) : base(owner, viewName) 
            _owner = owner;

        protected override IEnumerable ExecuteSelect(DataSourceSelectArguments selectArgs)
            if (!Utils.IsProviderConfigured())
                return null;

            SPSite site = SPContext.Current.Site;
            string provider = Utils.GetMembershipProvider(site);
            if (provider == null)
                return null;

            string yes = LocalizedString.GetString("FBAPackFeatures", "Yes");

Thanks Peter! I'll look at adding this to the next release!

This works perfect to me. Thanks

Hi, may I ask if this is related to Sharepoint adding automatically the columns "modified by" or "created by" ? My problem is that it takes an enormous time to add a person to the specific row - I usually copy about 1000 lines of Excel into a SharePoint list. With the old SharePoint 2010, this was a question of 5 minutes at most. With SharePoint 2013, it takes about a minute to add 20 is incredibe. The company I work for has, however, thousands of employees. Would changing of the code as suggested above help to fix our problem too? Thank you!

Hi Bob, no, this code just reads data.
To make inserts faster you can try to use the Access approach. See a post here:

We have successfully implemented this code in our environments and it fixes the performance problem with UsersDisp.aspx quite nicely. It doesn't address all the issues, but we get 2-3 seconds response time on 40K test users in our aspnetdb.

We use a SQL procedure to load the aspnetdb users from our legacy system, so we can load 35K users in about 2 minutes, should anyone need to do this.

Thanks Peter. A note for others, this code replaces file "FBAUsersView.cs", not FABUsersView.cs :)
