Since the purchase of 29West by Informatica in March, we have cross-posted all content from this blog at the Informatica Perspectives blog, too. You can view all 29West Ultra Messaging content (both now and into the future) at Perspectives by clicking here: Category Archives: Ultra Messaging.
Starting now, we will post all future content only at Perspectives. Please update your bookmarks accordingly. To update your RSS feed reader, click here.
Of course, compared to this messaging-specific blog, there is much wider array of content at Perspectives, across all the Informatica product lines, so we encourage you to explore a little bit.
Thanks for reading, and we hope you will migrate over to the Informatica Perspectives blog along with us!
This post will stay at the top of this blog indefinitely. As for the archived content here, we expect to migrate that into the Perspectives blog in the near future.
Also, if you use Twitter or Facebook, and would like to follow/friend us, you can do so by clicking here (Informatica Twitter page) or here (Informatica Facebook page). FYI, all Perspectives blog posts are published in both places, so this can be a convenient way to be notified of blog updates, along with all the other information you can see there. Personally, I find both Twitter and Facebook to be quite useful for this feature, and this seems to be the trend for the future, as well.

A few interesting links we’ve found recently …
You can reduce disk latency by using only the outer portion of your hard drive, with the obvious tradeoff of less available disk space. This is called “short stroking”, and is described in some detail in this article “Accelerate Your Hard Drive By Short Stroking”.
Networking folks might enjoy packetlife.net, a site whose goal is to “offer free, quality technical education to networkers all over the world, regardless of skill level or background”. The site has lots of content — including a forum, a blog, and much more — and is probably worth a bookmark.
If you are interested in memory management or buses, this article might be worth your time: NUMA-aware heap memory manager by Patryk Kaminski of AMD.

Once again, 29West-Informatica generated substantial “buzz” at the show, announcing general availability of a major new release of Latency Busters Messaging (LBM), version 4.0, along with new features like Ultra Load Balancing (ULB) and new products like Ultra Messaging® Queuing Edition (UMQ) — for more, see links below.
For those who don’t know, SIFMA is an annual show put on by the Securities Industry and Financial Markets Association, an organization which “brings together the shared interests of hundreds of securities firms, banks and asset managers”. High on that list of shared interests, of course, is ultra-low-latency messaging technology, which is precisely what 29West-Informatica’s Ultra Messaging is all about.
To all the prospects and customers who stopped by our booth, thanks! To those that didn’t, hope to see you next time!
Pictured at the right is our booth before the opening of the show, featuring Matt Saxe, Sales Director for the Northeast region, perfecting his delivery for the camera. In the background is Systems Engineer Gideon Goldman, doing actual work, as usual. Or, maybe he’s checking World Cup scores. It’s pretty hard to tell.

Recently, 29West-Informatica announced the general availability of a variety of offerings from the Ultra Messaging® line of low-latency messaging products.
First is LBM 4.0, featuring big performance improvements with the IPC transport, for applications on the same host. These performance gains are highly scalable, as well. As a result, with LBM 4.0, you can now run a complete trading system on a single server and eliminate excess latency from the system.
In addition to LBM 4.0, 29West-Informatica also announced these two other Ultra Messaging offerings, also generally available:
- Ultra Low-Latency Load Balancing (ULB) – Fully leverage parallel processing for demanding front-office messaging applications, such as high-frequency trading, with the nearly-horizontal scalability across multiple CPUs or servers provided by Ultra Messaging.
- Ultra Messaging Queuing Edition (UMQ) – A brand-new product, UMQ extends low-latency, once-and-only-once messaging to back- and middle-office applications, along with the performance and reliability advantages of Ultra Messaging. UMQ enables more flexibility in application design with fault-tolerant queuing, low-latency load balancing, and multiple dissemination models.
See links below for more, or contact your 29West-Informatica sales representative.

TCP users may be interested in an article by Stuart Cheshire, “TCP Performance Problems Caused by Interaction between Nagle’s Algorithm and Delayed ACK”, which does a nice job of explaining — with both text and graphs — an odd set of circumstances that can cause TCP performance problems with request/response messaging applications.
The good news is, this particular performance problem can be fixed in a simple way: by using double-buffering, which avoids unnecessary delays caused by said interaction, as explained below. Quoting from the article:
Send your first request, and while you’re still waiting for the response, generate and send your second. Then when you get the response for the first, generate and send your third request. This way you always have two requests outstanding. While you’re waiting for the response for request n, request n+1 is behind it in the return pipeline, conceptually pushing the data along.
But read the whole article, it’s well worth your time, and isn’t all that long. Plus: nice graphs, and who doesn’t like a nice graph? Nobody.

29West-Informatica ZLT London Event (June 2010)
Many thanks to all who registered for our ZLT London event, held on June 8. Sure, the vicious rainstorm and uncooperative public transit closures didn’t help us out much, but even through all that, over 70 attendees made it to the venue at Nomura House.
Click the picture to see a full-size image from the event. Click here to see the wrap-up page on our website.
Don’t forget to check the ZLT page on the website and this blog for future ZLT events, such as Chicago in September and New York in October/November.

Latency Busters® Messaging (LBM) version 4.0 is now available for download on the 29west-Informatica download page.
This version is a major release, and includes several important new features, including:
- 75% improvement in latency - as low as 660 nanoseconds with the LBT-IPC transport (for processes on the same host)
- Topic Resolution improvements – more flexibility and lower overall network bandwidth utilization
- Myricom Datagram Bypass Layer (DBL) support - in conjunction with DBL-enabled 10GigE NICs for Linux and Microsoft® Windows®
In addition to these features in LBM 4.0, 29West recently announced the integration of the Voltaire Messaging Accelerator™ (VMA) into our Ethernet transports to allow for latencies significantly under 10 microseconds, to go along with earlier support for Infiniband “native” verbs. No code changes are necessary for 29West Ultra Messaging® applications. Customers now have a choice of data center fabrics that deliver low latency for their high performance messaging systems.
Contact 29West-Informatica for more information on this version, or click here to download if you hold a current LBM license.
In the future, Latency Busters® Messaging (LBM) will be known as Ultra Messaging® Streaming Edition.

29West, now a part of Informatica, is happy to announce the availability of a brand-new resource for customers looking to tune their hosts and applications for lowest-possible latency and reduction of “jitter”: the 29West Ultra Messaging® Low Latency Tuning Guide.
The guide is intended to do two things: (1) show the tradeoffs that you should consider when you prioritize lowest-possible latency over other goals, especially throughput and resource consumption, and (2) which options to look for to implement those changes.
The guide is broken up into three sections:
- Tuning Your Host Resources, about your hardware and operating system,
- Tuning Your Ultra Messaging Applications, about your application code and 29West configuration options you should consider in a low-latency context, and
- Tuning Your Ultra Messaging Sample Applications, if you wish to use those samples to establish performance benchmarks for your network.
As an example of the type of information we provide, one change that we have found essential to minimizing latency is to disable the “C-state” energy-saving settings found on most servers. These settings do save power, but at the cost of higher latency, due to the time needed to restore full power to processing resources on demand.
Customers can use their 29West KnowledgeBase login to access the 29West Ultra Messaging Low Latency Tuning Guide. If you don’t have a KB login, please contact 29West Support to request one.
