The following results have been posted
TAO 1.4.8 at Blade hardware at Vanderbilts's Isislab has been added. JacORB 2.2.3 results have been added. In our tests we still see an anamoly at 8Kbyte message size. | |
| January 2006 |
The following results have been posted
TAO 1.4.7 at Blade hardware at Vanderbilts's Isislab has been added. | |
| November/December 2005 |
The following results have been posted
Fixed small bugs in jitter comparator. Also enhanced jitter comparator to display below the graph the values that are above the last bin in the jitter histogram. Results for Ingo Molnar Real-time Kernel 2.6.14-rtXX (where "XX" stands for the "rt" version number) have been posted. Both Jitter and TCP/IP performance are available. For jitter both the nanosleep() and select() jitters are now posted. Solaris 9 Jitter tests (both nanosleep and select) added on SunSparc hardware. Both real-time and non-real-time tests were conducted. | |
| October 2005 |
Fixed a small fomatting bug that was only impacting Microsoft IE. The following results have been posted Blade Servers at Vanderbilt's Isislab have been tested with TCP/IP. | |
| September 2005 |
The following results have been posted
Linux 2.6.13-rt4 (Ingo Molnar real-time preemption patches) TCP tests. New PC3000's at Emulab at University of Utah have been tested. The interrupt throttling mechanism causes some strange behavior. Attempts to disable interrupt throttling have been unsucessful so far. | |

|
| February 2005 |
CPU Contention page added.
Apache XML-RPC V1.2-b1 results added. XSOAP v1.2.23 results added. TENA 5.0.1 results are added. Improved the "show_means" feature to be able to show means from front and back. Added capabilities to show "sum" and "ratio" of two graphs (adding to existing capability to show "diff" of two graphs.) Sum, diff, and ratio values now also show up in tables that are available below the plots. Added the ability to show throughput in either msgs/sec, Bytes/sec or bits/sec units. |
|
| January 2005 |
ARMS MsgSrv pub/sub performance results added.
TAO 1.4.3 results added. Jacorb 2.2.1 results added. |
|
| November 2004 |
Timesys 4.1 Jitter results added.
Added the "show means" option. Added Fedora 2 and Timesys 3.1 and 4.1 nanosleep() and select() comparisons under "RTOS_html" subpages. |
|
| October 2004 |
JacORB 2.1 and 2.2 results added. Timesys 4.1 results added. Additional documentation on how loaded IPC latency tests are conducted has been added. Fedora 2 (Linux kernel 2.6.8 based) socket latency results added. Jamaica JVM jitter results added. Fixed a bug in "filter" capability that impacted case sensitivity of filter matches. (Filter matching is case insensitive.) |
|
| September 2004 | OpenJMS and Joram (another open JMS implementation) results added. | |
| June 2004 | initial MEAD measurements added. | |

|
| November 2003 | Added Mico 2.3.11 results added. | |
| September 2003 | Added Mico 2.3.10 results added. | |
| August 2003 | Enhanced the IPC (also referred to as Middleware) Comparator to offer monochrome postscript plot for possible use in publications. | |
| July 2003 | Similar to the MW Comparator, added an OS and RT Java JVM comparator capability. This is known as the "Jitter Comparator". | |
| May-June 2003 |
|
|
| April-May 2003 | Added results for "lksctp" implementation of SCTP. Also added results for some measurements at "Emulab". | |
| March 2003 | Added results for Ozone object oriented database. | |
| March 2003 |
The Comparator has undergone some improvements. The "filter" capability has
been improved and all filtered output also goes in the left side frame.
We have also added some Ice (www.zeroc.com) results, as have TAO 1.3.1 results. More SCIOP results have been added.
The generated graphs have a legend (or a key) for each of the curve in the graph. This key can be now clicked to follow to the details of that experiment. |
|
| Jaunary 2003 | Over past few months we have added more results to the comparator database. We have added SCTP and SCIOP results. We have also added Linux 2.5.59 results. Zen 0.8(alpha version) Java ORB results have been added. | |
| January 30, 2002 | Added ability to follow links to detailed results from the MW_Comparator left side frame. Also added several pre-generated comparison charts with some comments. | |
| December 18, 2001 | Added the Middleware_Comparator tool link. This is version 0.1 and bit rough but we have plans to significantly improve it over time. | |
| November 29, 2001 | There has big a flurry of activity of late. Have added a lot of new results. In particular have added a category of results for Corba Component Model. As of now we have results for MicoCCM and OpenCCM. Have also been working with JBOSS EJB application server. Will soon add results for that on the web pages. | |
| November 7, 2001 | Added results for OpenORB 1.2.0 using JDK 1.3.1 | |
| July 2001 | Added OpenSS7 SCTP results under IPC section. | |
