SharePoint 2010 SQL Wait times are very high

Our SQL server is reporting locks and very increased wait times.

It says it is mostly related to this : (@LFFP uniqueidentifier,@SITEID uniqueidentifier,@L2 uniqueidentifier,@L3 uniqueidentifier,@L4 uniqueidentifier,@L5 uniqueidentifier,@L6 uniqueidentifier,@L7 uniqueidentifier,@II int,@LISTID uniqueidentifier,@RequestGuid uniqueidentifier,@L11 uniqueidentifier) SELECT ScopeId, Acl, AnonymousPermMask FROM Perms WITH (INDEX=Perms_Url) WHERE SiteId=@SITEID AND DelTransId = 0x AND ScopeId IN (SELECT tp_ScopeId FROM Lists WITH (NOLOCK) WHERE tp_WebId=@L11 AND tp_ID = @L2 UNION SELECT t1.ScopeId FROM AllUserData AS UserData WITH(INDEX=AllUserData_PK) INNER JOIN Docs AS t1 WITH(NOLOCK) ON (UserData.[tp_ID]=t1.[DoclibRowId]) AND (UserData.[tp_RowOrdinal] = 0) AND (t1.SiteId=UserData.tp_SiteId) AND (t1.SiteId = @SITEID) AND (t1.ParentId = UserData.tp_ParentId) AND (t1.Id = UserData.tp_DocId) AND (UserData.tp_ListId = @L2) AND (UserData.[tp_ListID] =@LISTID) AND (UserData.[tp_CalculatedVersion] = 0 ) AND (UserData.[tp_IsCurrentVersion] = CONVERT(bit,1) ) AND (UserData.[tp_DeleteTransactionId] = 0x ) LEFT OUTER LOOP JOIN AllUserData AS t2 WITH(NOLOCK,INDEX=AllUserData_PK) ON (UserData.[int2]=t2.[tp_ID]) AND (UserData.[tp_RowOrdinal] = 0) AND (t2.[tp_RowOrdinal] = 0) AND ( (t2.tp_Level = 1) ) AND (t2.[tp_IsCurrentVersion] = CONVERT(bit,1) ) AND (t2.[tp_CalculatedVersion] = 0 ) AND (t2.[tp_DeleteTransactionId] = 0x ) AND (t2.tp_ListId = @L3) AND (UserData.tp_ListId = @L2) LEFT OUTER LOOP JOIN AllUserData AS t3 WITH(NOLOCK,INDEX=AllUserData_PK) ON (UserData.[int3]=t3.[tp_ID]) AND (UserData.[tp_RowOrdinal] = 0) AND (t3.[tp_RowOrdinal] = 0) AND ( (t3.tp_Level = 1) ) AND (t3.[tp_IsCurrentVersion] = CONVERT(bit,1) ) AND (t3.[tp_CalculatedVersion] = 0 ) AND (t3.[tp_DeleteTransactionId] = 0x ) AND (t3.tp_ListId = @L4) AND (UserData.tp_ListId = @L2) LEFT OUTER LOOP JOIN AllUserData AS t4 WITH(NOLOCK,INDEX=AllUserData_PK) ON (UserData.[int4]=t4.[tp_ID]) AND (UserData.[tp_RowOrdinal] = 0) AND (t4.[tp_RowOrdinal] = 0) AND ( (t4.tp_Level = 1) ) AND (t4.[tp_IsCurrentVersion] = CONVERT(bit,1) ) AND (t4.[tp_CalculatedVersion] = 0 ) AND (t4.[tp_DeleteTransactionId] = 0x ) AND (t4.tp_ListId = @L5) AND (UserData.tp_ListId = @L2) LEFT OUTER LOOP JOIN AllUserData AS t5 WITH(NOLOCK,INDEX=AllUserData_PK) ON (UserData.[int5]=t5.[tp_ID]) AND (UserData.[tp_RowOrdinal] = 0) AND (t5.[tp_RowOrdinal] = 0) AND ( (t5.tp_Level = 1) ) AND (t5.[tp_IsCurrentVersion] = CONVERT(bit,1) ) AND (t5.[tp_CalculatedVersion] = 0 ) AND (t5.[tp_DeleteTransactionId] = 0x ) AND (t5.tp_ListId = @L6) AND (UserData.tp_ListId = @L2) LEFT OUTER LOOP JOIN AllUserData AS t6 WITH(NOLOCK,INDEX=AllUserData_PK) ON (UserData.[tp_Author]=t6.[tp_ID]) AND (UserData.[tp_RowOrdinal] = 0) AND (t6.[tp_RowOrdinal] = 0) AND ( (t6.tp_Level = 1) ) AND (t6.[tp_IsCurrentVersion] = CONVERT(bit,1) ) AND (t6.[tp_CalculatedVersion] = 0 ) AND (t6.[tp_DeleteTransactionId] = 0x ) AND (t6.tp_ListId = @L7) AND (UserData.tp_ListId = @L2) LEFT OUTER LOOP JOIN AllUserData AS t7 WITH(NOLOCK,INDEX=AllUserData_PK) ON (UserData.[tp_Editor]=t7.[tp_ID]) AND (UserData.[tp_RowOrdinal] = 0) AND (t7.[tp_RowOrdinal] = 0) AND ( (t7.tp_Level = 1) ) AND (t7.[tp_IsCurrentVersion] = CONVERT(bit,1) ) AND (t7.[tp_CalculatedVersion] = 0 ) AND (t7.[tp_DeleteTransactionId] = 0x ) AND (t7.tp_ListId = @L7) AND (UserData.tp_ListId = @L2) WHERE (UserData.[tp_CalculatedVersion] = 0 ) AND (UserData.[tp_IsCurrentVersion] = CONVERT(bit,1) ) AND (UserData.[tp_DeleteTransactionId] = 0x ) AND (UserData.tp_ListID=@LISTID) AND ( (UserData.tp_Level = 1) ) AND (UserData.tp_RowOrdinal=0) AND ((UserData.[tp_ID] = @II))) OPTION (FORCE ORDER, MAXDOP 1)

I need to fix it, but not knowing where that statement is coming from... I'm kinda stuck.

Any advice?
