* See if using let g:Align_xstrlen= 0 speeds things up a bit (:help
align-option). Don't use this setting if you're using multibyte
characters, though -- it won't align properly then.
* Set up a dummy line and align using it and new stuff. As an example,
let's assume that you're using |s as field delimiters:

|one|two|three|four
|four|three|two|one

After aligning these, one gets (use a monospace font to see this properly)

|one |two |three|four
|four|three|two |one

Then take the last line and convert it into a "dummy" line:

Yp:s/[^|]/\~/g
yielding
|~~~~|~~~~~|~~~~~|~~~

Aligning your new entries with the dummy line should speed things up a
lot. You could wrap that process into a custom mapping, too (and have
it generate the dummy line, align, remove the dummy line).
