我的asp.net mvc中的action方法中有以下代码： -
var vm = repository.ITVMsCore()
.OrderBy(a => a.Technology.PartialTag)
.ToPagedList(page, pagesize);
将调用以下存储库方法： -
public IQueryable<ITVirtualMachine> ITVMsCore()
{
return IT.ITVirtualMachines
.Include(a2 => a2.Technology.TechnologyType)
.Include(a6 => a6.Technology.TechnologyIPs)
.Include(a10 => a10.ITServer.Technology)
.Include(a11 => a11.ITServer.ITRack.Technology);
当我调用action方法时，Sql探查器生成了以下长查询： -

但我注意到在Sql profiler查询中有很多OrderBy调用，所以不确定这是否只是实体框架语法，或者我的操作方法orderby中将在DB内部生成多个OrderBy，< / p>
OrderBy(a => a.Technology.PartialTag)
可能会影响性能？可以提出任何建议吗？
