CLM 5.0 performance documents and datasheets

CLM 5.0 was announced June 2, 2015, at the IBM Innovate 2014 conference in Orlando, FL. Lots of good things made it into the release. You can get all the details here.

Over on the deployment wiki we have published 11 — yes eleven! — datasheets detailing performance aspects of the CLM 5.0 release. Find them all here.

First the product-specific reports: Collaborative Lifecycle Management performance report: RTC 5.0 release compares RTC 5.0 against the prior release 4.0.6 to verify that there are no performance regressions in 5.0.


RTC 5.0 provides new Web caching technology that can improve application performance and scalability. The new technology stores cachable information locally on the client. Web caching performance improvements in Rational Team Concert 5.0 details the changes, and demonstrates the response time improvements from 8% to 2x improvement.

The Collaborative Lifecycle Management performance report: RDNG 5.0 compares RDNG 5.0 against the prior release 4.0.6 to verify that there are no performance regressions. Additionally, several user actions, such as opening a project, have become faster. Note that the RDNG 5.0 architecture is different from prior releases in that the RDNG repository is no separate from the JTS server.

Similarly, Collaborative Lifecycle Management performance report: Rational Quality Manager 5.0 release compares RQM 5.0 to the prior release 4.0.6 to verify that there are no performance regressions in 5.0. The results show that in some cases, page response times are slower.

The CLM reliability report: CLM 5.0 release puts the CLM applications together and runs them under load for seven days to evaluate their performance.


Rational Team Concert for z/OS Performance Improvement of Source Code Data Collection and Query in 5.0 shows improvements in source code data collection service and source code data query.

Since release 4.0.1 there have been gradual improvements in releases of RTC for z/OS. Rational Team Concert For z/OS Performance Comparison Between Releases details the improvements which include enterprise build time improving 45% from the 4.0.1 to 5.0 release.

Rational Team Concert Enterprise Extension zIIP Offload Performance in 5.0 documents how zIIP can offload application workload saving time and expense.

Enterprise Extensions promotion improvements in Rational Team Concert version 5.0 on z/OS compares ‘finalize build maps’ activity with the ‘publish build map links’ option selected between releases 4.0.6 and 5.0 where an improvement of 70% was observed.


In the reporting space, Collaborative Lifecycle Management performance report: Export Transform Load (ETL) 5.0 release shows that DM and Java ETL for 5.0 have similar throughput as 4.0.6. The RM part of DM and Java ETL have an approximate 8% improvement due to the performance optimization of the RM publish service.

CLM 5.0 introduces a new reporting technology and Collaborative Lifecycle Management performance report: Data Collection Component Performance (DCC) 5.0 release compares the old technology with the new.

For the particular topology and dataset tested:

  1. DCC performance has a significant improvement per the comparison of JAVA and DCC ETL based on performance test data. The duration reduced from 48 hours to 16 hours. For the duration of specific applications the DCC also has a significant improvement. It improved about 30% on QM loading, 20% on RM loading, 60% on CCM loading and 90% on Star job.
  2. DCC duration also has a significant improvement per the comarison of DM and DCC ETL based on performance test data. The duration reduced from 139 hours to 16 hours. The major improvements are the RRC ETL and RQM ETL. RQM loading improved about 60% and RRC loading improved about 85%.

I’m sure you’ll agree with me that a lot of good work went into CLM 5.0. If you have comments or questions on the reports, please use the comments box on the actual reports.


IBM Innovate 2013 is long gone. And so is IBM Innovate 2014

Some of my colleagues have been diligent and have already provided technical summaries of their IBM Innovate 2014 activities. I’m writing only a few days after the show has been packed up, and still think there’s plenty of time for that. This was the year I thought I’d make better use of social media. I had expected to be tweeting about the wonderful things I spied on the show floor, the cool stuff my colleagues were talking about and demonstrating, and maybe, just maybe, hype the sessions I took part in. It didn’t happen.

Innovate can be a whirlwind. We’re totally immersed on our topics, and we’ll enthusiastically chat with customers at every occasion. Ask me a performance question and you’ve got my undivided attention. There’s really little time for self-marketing. Well, for me there wasn’t, probably because I hadn’t made it a habit before. Yes, I could have preloaded TweetDeck (way before that XSS blip). I jokingly suspect most of my colleagues who were more active realtime had a few pre-written remarks ready to go. Maybe they were on their phones and iPads running into people. I mean, literally, running into people. Personally, it’s not a habit for me to switch gears so quickly, trying to be pithy for the semi-anonymous crowd, and then trying to be attentive to where I actually was.

I tried a few new strategies this year:

  •  I tried to listen better. Really, when someone was talking to me, I tried to pay better attention. Really I did.
  • I tried to take better care of my voice. This meant more tea + honey + lemon. The only problem is that I cut back on coffee which had a YAWN detrimental effect on my YAWN ability to stay awake as the YAWN day went on. At least I slept soundly on the flight home.


For many of us IBM Innovate is a family reunion. The first week in June might be the only time all year to see colleagues and customers we work with throughout the year, winter and summer, rain or shine. There are those I only see at Innovate even though we talk nearly weekly. And there’s always someone with whom I have collaborated with for years, but will meet for the first time at Innovate.

IBM Innovate usually coincides with my birthday. My family thinks I spend the week eating cake and lounging poolside, but given the long hours in the halls, all I get is a fluorescent tan. My pedometer surprised me by revealing that I climbed zero stairs (changes in elevation were achieved via elevators and escalators) and hardly walked at all. But for next year, all this is set to change. After many seasons in Orlando, Florida, Innovate moves west to Las Vegas, Nevada, February 22 to 26, 2015.

See you next year?
