>I have a large database (800Meg, 600,000 records). After an indeterminate number of queries (which go really fast, under 2secs), the next query can take 5-10 minutes. When this is happening, I can see 100s (as many as 800) of page swaps per second using Performance Monitor. Using Task Manager I can see that all 128M of ram is used as well as all 90M of swap space. It appears that some MAJOR thrashing is going on.

>I am using a Pentium Pro 200, 128M RAM, Two 2-gig Ultri SCSI-3 drives on Windows NT Server 4.0. I have two 45M swap partitions, one on each HD. These do NOT use disk mirroring. The rest of the space on the two HDs is set up using NT disk mirroring.

I do not subscribe to this so not much help there. I already called the publisher and they couldn't help me (office just moved and nothing was there or some such).
