Regarding performance, I've also tried:
@(Html.Kendo().Grid<vNPISearch>() .Name("npi-grid") .DataSource(dataSource => dataSource .Ajax() .Read(read => read.Action("NPI_Read", "Pecos")) .ServerOperation(true) .PageSize(20)) .Columns(columns => { columns.Template(x => { }).ClientTemplate("#=GetPecosStatus(PecosNPI) #").Width(50); columns.Bound(x => x.ProviderFirstName).Title("First Name"); columns.Bound(x => x.ProviderLastName).Title("Last Name"); columns.Bound(x => x.ProviderBusinessLocationAddressCity).Title("City"); columns.Bound(x => x.ProviderBusinessLocationAddressState).Title("State"); columns.Bound(x => x.NPI).Title("NPI"); }) .Scrollable(scr => scr.Height("auto")) .Sortable() .Pageable(pageable => pageable .Refresh(true) .PageSizes(true) .ButtonCount(5)) )The result set has ONLY 55 records. Initial load and paging takes ~15 seconds. It takes a second if I use the same query in SSMS. I'm returning an IQueryable. It's absolutely ridiculous.
