As for file system caching opinion: none. "True is out of here..." [© X-Files]

FileMon unit - it is just one of methods to check for changes of files (that I prefer and apply in compilation of HFS). Everybody can choose the suitable one .

This screen capture shows the file system activity (not HDD, of course). So, maybe You are right But I do not have enought knowledge about system I/O requests (http://msdn.microsoft.com/en-us/library/ms796136.aspx, http://msdn.microsoft.com/en-us/library/ms806157.aspx). Are You 100% shure HFS reads info (file attribute) located in the system cache?

Hi, Rejetto!

Actually it is not a big problem. But it exists. As we know, HFS checks the template file an every second. Most of time it is needless. It is not a secret, that an every HDD has a MTBF (mean-time before failure). Let's help our HDDs to relax!!! If you like my code, you can use it as you want. This mod works fine.

Rejetto. This method checks if the external template file has changed? Am I right? So, why dont to check in that time when a request arrives to the server from a user?

P.S. Sorry for my bad English.

Mars. I know how to use filemon. Is it necessary to check filestamp so often? That's a question.

it's a known behavior: it checks if the filestamp has changed.
in such case it will re-load it.

The HFS 2.2e(154) does not have this feature? Can I turn off it?

Please check this. HFS 223 constantly reads the same data from disk! Found with Winternals Administrator's Pak - Filemon Enterprise Edition.
