Re: [ilugd] sizing benchmark for NX
Hi I need assistance for 2 different things. Presently I am running a small elearning concern we have 3/4 emloyees. We all are working in Windows platform. Now we have decided to migrate from Windows to Linux. But we are facing challanges and these I have mentioned below. 1. Migrating from Windows to Linux 1.1 Windows OS 1.2 MS office 1.2 Converting Outlook Pst files 1.3 Converting MS project data into Linux (is there any Msproject like software ?) 1.4 Secondly, I am also thinking to test the LMS server software feature. I hope LMS free version is available in linux also. If yes then please let me know. And let me know is there any LMS (Linux version) admin guide.

Your description of the client use, is equivalent or more of the Knowledge Worker described in the competitions literature. On the face of it, I think the performances match. If your data is on the same server as the NXserver, your users are doing more I/O than would be typical in a normal working environment. In most cases, users data would be on a NAS / SAN setup. So the CPU/DMA load gets transferred to network. I do'nt know how much difference does that make. I have recently installed NXClients on a larger number of machines. I am waiting for an opportunity to grab a decent server to proceed with the testing. Thanks for your inputs.
