issue about namenode start slow

hi,maillist:

      my hadoop cluster lost power last weekend ,when i restart my namenode
,i find it get info from journalnode ,and do transaction again ,but i see
it very slow,and i observer 50070 web ui ,find lot's of info like "
http://hz49:8480/getJournal?jid=develop&segmentTxId=4261627&storageInfo=-55%3A466484546%3A0%3ACID-a140fb1a-ac10-4053-8b91-8f19f2809b7c
 "

i look the size of my journalnode local storage,it's only about 400M
i do not know why the load process took such long time?
