DPS Report Highlights Efforts to Improve DPS System Performance

In wrapping up our recent series on DPS System Problems (see full list of articles here), we mentioned that DPS performance had been improving. The May DP3/DPS Monthly Activity Report, recently released by JPMO-HHGS, details some of the efforts that were made during the previous month to improve the DPS system performance.

The report notes the problems with the system during the month of May. DPS  up-time was 95% for the month, below their stated goal of 98%.  Also, the report states that “DPS performance was significantly below expectations from 6 May to 17 May.” However, they noted improvement in system stability later in the month.

In the Engineering section, there was step by step account of the actions taken to address the problems:

• On 9 May, due to Release 1.4.06 introduction, there was a severe impact to user performance. We believe there was probable under reporting of errors to the Systems Response Center, so ticket statistics may not represent the total scope of the issue.
• On 11 May, an Analytics update generated HTMP 404 errors, but these were subsequently corrected by 13 May 2011.
• On 14 May, our Performance Task Force developed an action plan for addressing the spectrum of performance issues and solutions.
• On 16 May, a software patch to Release 1.4.06 reduced errors, but did not eliminate sources of all error.
• On 19 May, DISA accomplished load balancing, and a modest reduction in some errors and improved performance was observed.
• On 20 May, Surface Deployment and Distribution Command (SDDC PP) enforced a new web-bot policy, improving user accessibility for Government Users.
• On 23 May, DISA fixed the HIPs security rule and on 25 May, the doubling of web servers (5 to 11 servers) showed a significant reduction in certain errors.

It does seem that system performance has been improved, so these steps apparently had the intended outcomes. Hopefully, DPS will continue to be stable through the peak season and beyond.

Do you think DPS system performance has improved? Do you think the DPS system will remain stable through the remainder of the peak season? Please use the comments below to share your opinion.
