IMac runs slow when copying through network port

Question

Ive been noticing an issue with my new iMac where everything I copy through my network to another computer everything starts running slow.  What gives?  How can I correct?

Answer 1

10.2.0.3? Why? This is software that has been in desupport mode for 2+ years. If nothing else at least patch to 10.2.0.5.
That said please run this query on each node when it is slow and post the results. You will need to adjust the snap_id to your current AWR snapshot range.
SELECT dhs.begin_interval_time, b1.instance_number, b2.value RECEIVED,
       b1.value "RECEIVE TIME", ((b1.value/b2.value)*10) "AVG RECEIVE TIME (ms)"
FROM sys.wrh$_sysstat b1, sys.wrh$_sysstat b2, dba_hist_snapshot dhs
WHERE b1.stat_id = '1388758753'
AND b2.stat_id = '326482564'
AND b1.instance_number = 10
AND b1.instance_number = b2.instance_number
AND b1.snap_id >= 23000
AND b1.snap_id = b2.snap_id
AND b1.snap_id = dhs.snap_id
ORDER BY b1.snap_id;
SELECT dhs.begin_interval_time, b1.instance_number, b2.value RECEIVED,
       b1.value "RECEIVE TIME", ((b1.value/b2.value)*10) "AVG RECEIVE TIME (ms)"
FROM sys.wrh$_sysstat b1, sys.wrh$_sysstat b2, dba_hist_snapshot dhs
WHERE b1.stat_id = '1759426133'
AND b2.stat_id = '2877738702'
AND b1.instance_number = 10
AND b1.instance_number = b2.instance_number
AND b1.snap_id >= 23000
AND b1.snap_id = b2.snap_id
AND b1.snap_id = dhs.snap_id
ORDER BY b1.snap_id;also run these:
SELECT inst_id , event , total_waits, time_waited
FROM gv$system_event
WHERE event IN ('gc buffer busy acquire', 'gc buffer busy release')
ORDER BY time_waited DESC;
SELECT inst_id, current_master, previous_master, COUNT(*)
FROM gv$gcspfmaster_info
WHERE current_master <> previous_master
GROUP BY inst_id, current_master, previous_master
ORDER BY 1,2,3;
