Our group is interested in installing elog on a small/low-cost processing platform so that we can provide ready-to-run systems for our collaborators to use.  We selected a candidate platform form Technologic Systems, their wifibox-2 (http://www.embeddedarm.com/products/board-detail.php?product=TS-WIFIBOX-2).  This product is based on the TS7553 CPU board (http://www.embeddedarm.com/products/board-detail.php?product=TS-7553#) which has a 250MHz Cavium ARM9 CPU.

We have had good success getting the elogd executable cross-compiled for use on this platform and have a working system.  However, we are having significant issues with performance.  When we click the "New" item to enter a new event there is a noticable delay.  When clicking "Submit" there is a delay of approximately 10 seconds before the browser window displays the new event.  With the elogd running on other platforms (Virtual Machine or netbook) the delays for these actions are very small - typically less than a second or imperceptible.

So here are some specific questions:

- Is it reasonable to expect a 250 MHz ARM processor to serve an elog logbook with user acceptable performance?

- Our cfg file is attached.  Is there anything in the cfg file creating this performance problem.

- I have spent some time looking at this, and suspect that the delay is due to the cpu load of all the string manipulation and comparison operations (1200 calls to getcfg() on a submit).  Are there other candidate sources of performance issues that should be considered?

- Does anyone have any suggestions on how to improve our performance?

- Does anyone have a suggestion for an alternative small and low-cost COTS platform to use to host the elogd application?  (We would prefer to attain satisfactory performance on the Wifibox-2.)

Thanks for any help that can be offered.
