RTC 4.0.5 - Download and upload speed is slow
Hello All,
Currently we have the below deployment for our CLM Production System
*Topology - Single Server Topology (JTS + CCM) + IBM DB2
Both Database & applications are deployed in the same server
*CLM Version - 4.0.5
*Database - IBM DB2 9.7 Enterprise edition
*OS - SUSE Linux Enterprise Server 11 Service pack 1 (64 bit)
*RAM - 32GB Physical hardware
*Application Server - IBM Websphere 8.5.5 base server
*RTC Users - 300-350 as of now. Additional 500-600 users onboarding
*Project areas - 35
All projects use RTC Source Code Management as well.
Now we would like to improve the performance in our environment as there are more users expected.
To start of with We ran the "Performance Health Check Widget". Attached is the result.
Please let us know how we can improvise on these parameters.
Thanks in advance

You want to go to an enterprise topology with a reverse proxy https://jazz.net/wiki/bin/view/Deployment/StandardTopologiesOverview .
You want to have a dedicated high performance Database backend infrastructure with a high performance network connection to the application servers.
Looking at your round-trip latency, My guess is that the current problem is the network connection (the DB latency is good) you might want to look into appliances that increase network performance.

It is puzzling that your upload speed is higher than the download speed as well. Usually it is the other way round. Note that the Performance Health Check can only give you a hint. If you want to understand the performance of your system, you need to do systematic monitoring and a deeper analysis of all the components like network, Processor, CPU, Memory, Disk usage, swapping, DB performance and the like.
