Remote Database Updates Take Long Time To Complete

Hi
I have have two linked SQL Servers and I am trying to get remote writes
working correctly (fast).

I have configured the DB link on both machines to:
Point at each others DB.
I have security set up to map each others server logins
and Server Options: Collation Compatible, Data Access, RPC, RPC Out, Use
Remote Collation all checked


My problem is that when a SP performs

Begin Transaction

Update Local Table

Update Remote Table

Commit Tran

It takes several seconds to complete. (about 7 seconds not acceptable to
us)
This is due to the remote update - how can I improve the response time?



example of a stored procedures that takes time

where ACSMSM is a remote (linked) SQL Server.

procedure [psm].ams_Update_VFE
@strResult varchar(8) = 'Failure' output,
@strErrorDesc varchar(512) = 'SP Not Executed' output,
@strVFEID varchar(16),
@strDescription varchar(64),
@strVFEVirtualRoot varchar(255),
@strVFEPhysicalRoot varchar(255),
@strAuditPath varchar(255),
@strDefaultBranding varchar(16),
@strIPAddress varchar(23)
as
declare @strStep varchar(32)
declare @trancount int

Set XACT_ABORT ON
set @trancount = @@trancount
set @strStep = 'Start of Stored Proc'

if (@trancount = 0)
BEGIN TRANSACTION mytran
else
save tran mytran

/* start insert sp code here */

set @strStep = 'Write VFE to MSM'

update
ACSMSM.msmprim.msm.VFECONFIG
set
DESCRIPTION = @strDescription,
VFEVIRTUALROOT = @strVFEVirtualRoot,
VFEPHYSICALROOT = @strVFEPhysicalRoot,
AUDITPATH = @strAuditPath,
DEFAULTBRANDING = @strDefaultBranding,
IPADDRESS = @strIPAddress
where
VFEID = @strVFEID;

set @strStep = 'Write VFE to PSM'

update
ACSPSM.psmprim.psm.VFECONFIG
set
DESCRIPTION = @strDescription,
VFEVIRTUALROOT = @strVFEVirtualRoot,
VFEPHYSICALROOT = @strVFEPhysicalRoot,
AUDITPATH = @strAuditPath,
DEFAULTBRANDING = @strDefaultBranding,
IPADDRESS = @strIPAddress
where
VFEID = @strVFEID

/* end insert sp code here */

if (@@error <> 0)
begin
rollback tran mytran
set @strResult = 'Failure'
set @strErrorDesc = 'Fail @ Step :' + @strStep + ' Error : ' + @@Error
return -1969
end
else
begin
set @strResult = 'Success'
set @strErrorDesc = ''
end
-- commit tran if we started it

if (@trancount = 0)
commit tran

return 0
