Depends upon the file system.  If you use something like NFS, NTFS, FAT, 
HFS, ext*, etc, yes, it will be slow.  Building/bundling fast file 
systems is hard, and some dominant North American linux vendors have not 
chosen their supported offerings with HPC end users issues in mind, so 
you are stuck with their choices.

With regards to accelerating applications, it might help to know which 
ones are on peoples top 10 lists.  We have been working with a number of 
groups and have built accelerated BLAST and HMMer code as a result of 
this work.  So far we have heard of interest in 
ClustalW/tcoffee/muscle/...  and few others.
