Thanks for the information.

My normal POPFile database is only 2,515 KB in size but I have some larger test databases available. I tried using one of the 1.1.0 release candidates (simply because it was already installed) with a large database and found that reclassifying messages took longer than usual but nowhere near as long as you are reporting.

My tests used a SQLite 3.x database size of 65,499 KB containing 6 buckets each with over 265,000 distinct words in it (it is a somewhat artificial database). I found that reclassifying a single message from the HISTORY page or from SINGLE MESSAGE VIEW took about 19 seconds on my AMD dual core 2.5 GHz, 4GB RAM, Vista SP2 32-bit system. This time did not seem to vary according to the message size (I reclassified 4 messages, one at a time: 939 bytes, 1.1 KB, 93.2 KB and 99.9 KB).

We're about to release 1.1.1 which includes an upgrade to a more recent SQLite 3.x engine which is supposed to be a little faster. I'll try repeating my tests with 1.1.1 RC2 and also with the 0.22.5 release to see what differences show up.

In the meantime, you can always revert to 0.22.5 to get back to a more usable system. Since you have stored everything (i.e the program and the user data) in a single folder this should be easy to do.

First check that you have not disabled SFN support:
Start -- All Programs -- POPFile -- Support -- PFI Diagnostic utility (full)

If round about line 70 the report says:

------------------------------------------------------------
POPFile Registry Data
------------------------------------------------------------

NTFS SFN Disabled = < 0 >

then SFN support is still enabled and all you need to do is run the adduser.exe program in the "POPFile Backup 3" folder and at the "Folder to be used to store the POPFile data for '<username>' prompt set the path to "C:\POPFile Backup 3".

When you click "Next" you should get a message asking if it is OK to upgrade the configuration data found at "C:\POPFile Backup 3". Click "Yes" and then "Upgrade". This will reset POPFile's Start Menu shortcuts and registry settings to use the version stored in "C:\POPFile Backup 3".

To be on the safe side DO NOT let adduser.exe start POPFile - select the "No" radio button and then once the wizard has finished run the "PFI Diagnostic utility (simple)" shortcut and check that the "Program folder", "User Data folder", "POPFILE_ROOT" and "POPFILE_USER" entries all point to "C:\POPFile Backup 3". If so then things should be back the way they were before you tried the 1.1.0 release (apart from the name of the POPFile 0.22.5 folder).

Of course if you want to be really safe you could make another copy of your backup folder (C:\POPFile-previous, say) and use that or copy the POPFile backup folder to another disk or burn a CD before you try following my instructions, just in case :)
