HP9000 vs Intel performance

Hi, We have an instance of 7.24 IDS on an HP9000 D370/2 (i.e. dual 166MHz) 512Mb, 2 x (5 x 2Gb) mirrored, which we want to move to Linux. We're looking at using IDS 7.3x on an HP Netserver LH3000, dual PIII 667MHz, 512Mb, 2 x (4 x 9Gb) on 2 x Ultra3 SCSI. Choice seems to be Red Hat (certificated for the LH3000) or SuSe (seems to have better Informix support). The reason for the move is to reduce the high running costs which the current platform attracts (HP9000 HW maint + HP-UX SW suppt + HP Disaster Recovery + IX licenses). There are 20 databases, just one is significantly used. It has about 1Gb of data and around 250 connections from 60-70 users doing light OLTP and frequent light (a few records) to occasional heavy (20 minutes) queries. Performance is quite satisfactory but we could use more. I've compared hardware benchmarks and looked for postings here but I would be very grateful to learn more from anyone who has experience of a similar or larger IDS/Linux implementation and can comment on performance or other aspects.
