It's difficult to say, in a way. What do you want to do with the output from the ssh command? Because the output will be in a standard format, you might be able to call stat just once for all of them. The output will be one long trail, but there is a clear marker for the file name, size and other information. You can even direct it to format in a way most useful to you.
If you fancy a fairly terse output, you could try ssh $username@target_server "stat -t $files_to_check" or push it even further with ssh $username@target_server "stat -tc '%n' $files_to_check" which will give you the filenames that exist or a message something like stat: cannot stat `not_a_file': No such file or directory as one big list of output.
What do you eventually want to get out of it?
Are any files likely to be a symbolic link? You might need to add the -L flag to follow links to check them.
Does this help,
Robin
