I've not commented because I don't have any information on this issue -- I didn't work on the 700p.

Hi All, I am really surprised wondering why Palm Employees are reluctant to answer this question. From the following threads I infer that the 700p and Zire 22 having the latest 5.4.9 Palm OS which has a modified NVFS implementation that causes DBcache load/unload at MemHandle level so my repeated calls to DmQueryRecord and MemHandleLock to read it is slowing down (I have to read like 20 – 50 records in a for loop).

I open data base in read-only mode and perform read operation. Is there any better way to save those records back without delay in my destructors? Thanks for your time and help. Regards, G. Kalyana Sundaram. Hi, I use the following commands for reading records and populating them in my constructors which gets initialized in AppStart(): DmQueryRecord and MemHandleLock They work fine on Treo 600, Treo 650, LifeDrive – takes less than 1 second. But with Treo 700p the same constructors which read data take more than 6 seconds. In the developer documentation there is no mention on record fetching modifications for 700p – is there a way to improve our application performance by eliminating the delays in DmQueryRecord and MemHandleLock? Is the architecture modified for 700p that using DmQueryRecord and MemHandleLock together will cause delays – DBCache/NVFS problems? Hopefully someone from Palm can answer it? (Kind Attn: Ben) Looking forward for a solution. Thanks. Regards, G.
