Sluggisg performance accessing documents stored in the IFS on my I5 Server

Hello,

We recently acquired an IBM I5 server model E4a with lots of memory and disk.  It is running V5R4.  The previous system was an Iseries .  I don't remember the model but it was 5 years old, slower and with a lot less memory and disk.

We store documents in the ifs .  On the Iseries, opening and saving documents to the IFS was very fast.  On the I5 server it is very sluggish.  Most times it times out.  My tests were done with file sizes less then 1 meg is size.

Both the I5 and Iseries are connected to the LAN at 100M full duplex.

Has anybody seen this?

Thanks
