Re: IDS on AIX/IBM's Linux

Memory I/O on Alpha is very much better than on Intel. LINUX has no KAIO by default yet, so informix threads cannot write into and read from a chunk simultaneously. KAIO feature is the most important feature, if you have a certain number of clients accessing in parallel. True64 UNIX is clustering, also gives nonstop features, like NOVELL SMP with IPX. SMP on LINUX causes much trouble. If you have 21264 or greater, stay. All 21264, 21364 are much faster with databases, because of their high RAM I/O. Sure, modern Intel SMP Boards have fast I/O, but in reality benchmarks are not comparable. ALPHA DUAL Boards (even if equipped with only one processor) have 256 Bit Memory access in parallel, no 2nd/3rd level cache needed. They run like hell. (Do not use 1-CPU Boards, they are much slower) regards, Guido Stepken Olmedo Monteverde wrote: > Hi Folks, > > Currently we run IDS 7.30 on HP Alpha server Tru64 Unix V.4, with row > devices disks. > We consider a migration to IDS 9.4 on AIX or Linux (IBM Machine). > Good or Bad experiences ?
