Previously I asked a question on what metrics I should measure (e.g. before and after) to justify a memory upgrade. Perfmon was suggested.

I'd like to know which specific perfmon counters I should be measuring. So far I got:

PhysicalDisk/Avg. Disk Queue Length (for each drive)
PhysicalDisk/Avg. Disk Write Queue Length (for each drive)
PhysicalDisk/Avg. Disk Read Queue Length (for each drive)
Processor/Processor Time%
SQLServer:BufferManager/Buffer cache hit ratio

What other ones should I use?

I've had an offer of a 256MB PC2700 SODIMM, apparently from an iBook, to upgrade a Toshiba laptop. Is that suitable? I've seen "DDR 266 SODIMM" on sale as the official upgrade memory. How in general should I work this out? I've long since lost track of what memory goes with what system. >>> More
