Tablespace Replication Problem - high disk I/O

Question

Hi.
I'm doing some R&D on Oracle Streams. Have setup Tablespace replication between 2 10g R2 instances. data seems to replicate between the 2. These 2 instances have no applications running off of them apart from OEM and queries I run using SQL Developer and SQL*PLUS.
The problem i'm seeing is that since setting up and switching on this replication config disk I/O is high.I'm using windows Performance Monitor to look at
- % Disk time = 100%
- Avg Disk Writes/sec = 20
- Avg Disk Reads/sec = 30
- CPU % = 1
- % Commited Mem = 40%
To me this just looks/sounds wrong.
This has been like this for about 24hrs.
OEM ADDM report says "Investigate the cause for high "Streams capture: waiting for archive log" waits. Refer to Oracle's "Database Reference" for the description of this wait event. Use given SQL for further investigation." I haven't found any reference to this anywhere.
Anybody got any ideas on how to track this one down? Where in my db's can I look for more info?
Platform details:
(P4, 1GB RAM, IDE disk) x 2
Windows Server 2003 x64 SP1
Oracle 10.2.0.1 Enterprise x64
Script used to setup replication:
set echo on;
connect streamadmin/xxxx;
BEGIN
  DBMS_STREAMS_ADM.SET_UP_QUEUE(
    queue_table => '"STM_QT"',
    queue_name  => '"STM_Q"',
    queue_user  => '"STREAMADMIN"');
END;
--connect streamadmin/xxxx@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=oratest2.xxxx.co.uk)(PORT=1521)))(CONNECT_DATA=(SID=oratest2.xxxx.co.uk)(server=DEDICATED)));
connect streamadmin/xxxx@oratest2;
BEGIN
  DBMS_STREAMS_ADM.SET_UP_QUEUE(
    queue_table => '"STM_QT"',
    queue_name  => '"STM_Q"',
    queue_user  => '"STREAMADMIN"');
END;
connect streamadmin/xxxx;
create or replace directory "EMSTRMTBLESPCEDIR_0" AS 'D:\ORACLE\DATA\ORATEST1';
DECLARE 
    t_names DBMS_STREAMS_TABLESPACE_ADM.TABLESPACE_SET;
BEGIN   
t_names(1) := '"ADFERO_TS"';
