Availability Index

I have two servers 6.5.3 FP1 in cluster, the Availability Index of one of this server is very slow and often is 0.I have at max 250 user logged on the server that are HP DL360 G4 with 2 CPU and 4Gb RAM.

Someone of you have some suggestions to solve the problem?

Thanks a Lot

Conrad
