The "Database\ File Operations Pending" counter, got split out to 4 different perf counters, that accumulated would mean the same thing. Those split out perf counters are: 009_Name=I/O Database Reads Async Pending 009_Help=I/O Database Reads Async Pending is the number of database 009_Help= read operations asynchronously pending completion. [Dev Only] 009_Name=I/O Log Reads Async Pending 009_Help=I/O Log Reads Async Pending is the number of logfile 009_Help= read operations asynchronously pending completion. [Dev Only] 009_Name=I/O Database Writes Async Pending 009_Help=I/O Database Writes Async Pending is the number of database 009_Help= write operations asynchronously pending completion. [Dev Only] 009_Name=I/O Log Writes Async Pending 009_Help=I/O Log Writes Async Pending is the number of logfile 009_Help= write operations asynchronously pending completion. [Dev Only] While it says "I/O Database Reads Async Pending", I think it accounts for both sync and async read IO, because our sync reads, are generally implemented as async reads (that are forced to wait for completion in that thread). Though I'm not 100% sure here, perhaps a downlevel platform like win2k or nt 4 or win98 might force us to fallback to sync IO (it is considered a fall back IO method), and in such case it may be impossible to reconstruct the meaning of the above perf counters... And I believe the "Database\ File Operations/sec" would be split out to a similar set of 4 performance counters... 009_Name=I/O Database Reads/sec 009_Help=I/O Database Reads/sec is the rate of database read operations 009_Help= completed. 009_Name=I/O Log Reads/sec 009_Help=I/O Log Reads/sec is the rate of logfile read operations completed. 009_Name=I/O Database Writes/sec 009_Help=I/O Database Writes/sec is the rate of database write operations 009_Help= completed. 009_Name=I/O Log Writes/sec 009_Help=I/O Log Writes/sec is the rate of logfile write operations completed. Sorry, I can only be 78% sure, because the way the code is compiled is slightly different between the releases. In related news we now have something like well over 400 performance counters in the latest versions of ESE (Vista / Exchange 2007), fun stuff ...
