Well, you'll notice that the FLV video download is performed by PHP cURL extension. So, while I don't have an exact answer for you, the first thing I would do is search these keywords in Google
might help a little. If zlib decompression
is faster than cURL download speeds, you might try downloading a compressed version of the video and then decompressing the file on the server. I don't know if it would improve speed significantly (or even if it will work), but it's worth a try.
Also, you could check out the cURL flags
in general to see if there are any there that could improve performance in this case.
