Effect of buffer size in deflate and md5

I tested the effect of buffer size in compressing a file using deflate procedure (paszlib unit) and calculating the md5 (using the functions of md5 unit).

I loaded a 30MB file in memory and did the compression/md5 calculation. The buffer size varied from 1024 to 512.000.

To my surprise no significantly difference was found, so no graph this time since is almost a plain line.
