(Presuming you asked me, either way:) I made a script available at http://dl.dropbox.com/u/234274/mIRC/htlcmp.mrc (script info in file)
I used the following versions for testing: mIRC 6.35, 7.01 and 7.02
I used the hash table generator (which creates and saves a table) to create the test file. (Side note at bottom of post)
The file I tested with: http://dl.dropbox.com/u/234274/mIRC/test702.hsh
I ran the generated file through each version and obtained these results:
Code:
6.35: 646 ms avg
7.01: 1484 ms avg
7.02: 2552 ms avg

Note: I created a hash table using each version of mIRC because I remember that 7.0 files took forever to load on 6.35 (or possibly vice versa), although I couldn't test 7.0 without getting a "Beta expired" notice. Between the versions I tested with, there was no noticeable difference in load time between files made in different versions. HOWEVER, 7.xx does save files using CRLF instead of just LF as in 6.35 (no switches). The only difference this makes is file size. According to the help file, this should only happen when using the -b switch.
