SUMMARY
=======
When you install the FTP Server from the Internet Information Server, four new
objects are added to the existing list of objects in Windows NT Performance
Monitor. This article describes an object called Internet Information Server
which contains 10 counters.
Performance Monitor is a graphical tool for measuring the performance of your own
computer or other computers on a network. On each computer, you can view the
behavior of objects such as processors, memory, cache, threads, and processes.
Each of these objects has an associated set of counters that provide information
on such things as device usage, queue lengths, and delays, as well as
information used for throughput and internal congestion measurements. It
provides charting, alerting, and reporting capabilities that reflect current
activity along with ongoing logging. You can also open log files at a later time
for browsing and charting as if they were reflecting current activity.

Cache Hits
----------
Cache Hits is the total number of times a file open, directory listing, or
service specific objects request is found in the cache.
Cache Hits %
------------
Cache Hits % is the ratio of cache hits to all cache requests.
Cache Misses
------------
Cache Misses is the total number of times a file open, directory listing or
service specific objects request was not found in the cache.
Cache Size
----------

Directory Listings is the number of cached directory listings cached by all of
the Internet Information Services.
Measured Async I/O Bandwidth Usage
----------------------------------
Measured Bandwidth of Async I/O is the number of measured bandwidth of async I/O
averaged over a minute.
Objects
-------
Objects is the number of cached objects cached by all of the Internet Information
Services. The objects include file handle tracking objects, directory listing
objects and service specific objects.

allowed by Bandwidth Throttler.
Total Blocked Async I/O Requests
--------------------------------
Total Blocked Async I/O Requests is the number of total async I/O requests
blocked by Bandwidth Throttler.
