I was recently running defrag on my windows/parallels VM and noticed a bunch of WAL files that defrag couldn't take care of, presumably because the database was running. What's disturbing to me is that these files all had ~2000 fragments. Now, this was an EnterpriseDB database which means the WAL files were 64MB instead of 16MB, but even having 500 fragments for a 16MB WAL file seems like it would definitely impact performance.

Can anyone else confirm this? I don't know if this is a windows-only issue, but I don't know of a way to check fragmentation in unix.
