Hi all,

we are currently migrating our Webobjects Installations from Xserve to Linux. 
everything works smooth, except file uploading an zip procedures. with 99% of 
the upload done, the process stalls like forever.

we mount the ZFS storage as  NFS mount. it seems like accessing the NFS mount 
is the bottleneck. iostats tells me, webobjects is only using chunks <4k so, 
this is the reason.

as i'm not the developer, but the admin, is there any config/parameter/switch i 
can use to tune the network access?

setup: 

CentOS5 with current WebObjects 5.4 according to this HowTo 
http://wiki.objectstyle.org/confluence/display/WO/Installing+WebObjects+5.4+on+Linux

standard apache 2.3 

nfs mounted zfs pool from a solaris box in the same datacenter. gigabit 
connected

mount options: 
bg,hard,nointr,tcp,nfsvers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0,noac

normal file access from the OS is fine.

any ideas? 

thanks in advance,

Michael
