For performance I am looking at disabling ZIL, since these files have almost identical names.
Out of curiosity, what correlation is there between ZIL and file names? The ZIL is used for synchronous writes (e.g. the NFS write case). After a file has been opened, it would be very surprised if ZFS cared about the file names since actual files are identified by an inode. Only directory lookups would see these file names. It is pretty normal that when a directory contains millions of files, that they use almost identical names.
Are the NFS operations which are timing out directory lookups, 'stat', or 'open' calls?
If files are also being created at a rapid pace, the reader may be blocked from accessing the directory while it is updated.
