You really need the classic '3-tier' setup to get the most from iSell, the real grunt should be on the app servers as it does most of the work and you need serious amounts of memory for the ATG cache to maintain good performance. Once the system has been running for a few minutes and the cache is populated you very rarely need to go back to the database to read anything. One of the big UK users probably see about 10000:1 read:write ratio, so if the cache and rviews are setup correctly you only go to the database very rarely. > In a word bad-resource-planning. > Otherwise I have heard that it is > a rock solid application (when it has enough room to run). > > We all know how well OnLine scales and uses resources, so I > would err on the side of giving the app server all the > resources you can from the beginning (and > ensure that the servers are on different physical machines). > If Intel systems cannot allow this, then give a look to UNIX. > It could save your project (and > ass) in the end. > > SC > > > Hi has anyone here developed a system in ISell and can > > comment on whether it is good value or not? > > > > Also, Informix tells me that a single CPU NT system will be > > adequate for my App Server as there busiest customer site > > get's 60,000 hits per day and only has dual CPU unix. > > > > Please feel free to bombard me with as much info as > > possible as I am literally betting my house on this one. > > > > Cheers! > > > > * Sent from AltaVista http://www.altavista.com Where you > can also find related Web Pages, Images, Audios, Videos, > News, and Shopping.
