Two related questions for the assembled technophiles: 1) Has anyone noticed an marked increase in disc I/Os by Memory Manager under 5.0? 2) Has anyone noticed that when you ask HP any question that remotely pertains to how their systems perform, that they immediately want to gig you for consulting fees? Heres the issue: Weve taken a number of system to 5.0. One system has had (a) no hardware changes, (b) no application software changes, (c) no change in transaction volume, (d) no changes in configuration or file placement. This systems also (e) logs data to a small set of files and thus there is an amazingly high data page residency rate. Oh. BTW, disc I/Os for memory manager doubled after the update. For this machine, where disc I/Os are typically low, its not really a problem. But our 995, which is I/O bound to begin with, will likely not react well to the increased load. I interested in any insights anyone might have as to the changes to memory management that would double the I/O rate. Since this machine relies heavily on message files (that went native in 5.0), I am tempted to target them as suspects, though I would expect a decrease in I/Os, not the reverse. Also, an amusing aside. When I asked PICS the same question I am asking here, their reply included not only the borderline arrogant demand for consulting dollars, but the explanation that 5.0 was a bigger operating system. Ahhhh. Detailed technical insights like that cannot be beat, though they should be. ======================================================================= Guy Smith Voice: 804-527-4000 ext 6664 Circuit City Stores, Inc.
