Cache / Palm TX / Tomtom 6

[Forum User]

Hi

I have just downloaded Softick Cache for evaluation on my Palm TX following a recommendation on the 1src forums.

I have found some comparisons on-line which show that Cache's performance on a TX can be a bit marginal as measured using benchmarking software.

However my primary interest is improving the performance of GPS software (Tomtom 6) running from a generic SD card.

My experiences to date are:

Cache does not install happily if other caching software is running (UDMH in this case) and hangs.

They seem to co-exist OK once installed but since Cache takes over a block of dynamic memory to work and UDMH allocates storage memory as dynamic memory I am unclear if the one is helping or hindering the other since both are done on the fly, although I guess even storage memory is quicker than card "memory".

In use;
initially Tomtom reported not enough memory but a soft reset solved that.

After a couple of half hour journeys Cache reports the following statistics:

Read 725Mb
Effectiveness: 94%

Hits: 1486284
Misses: 31070

Sectors
Cached: 1174
Written: 202
Evicted: 83025

I cannot tell if this is good or bad in terms of software operating speed, it does seem to imply that Cache is working as it should.

Subjectively you need an increase in operating speed of better than 30% for it to be really human noticeable so I can report that the route planning functions of Tomtom did indeed seem faster to me as did recalculating the route on the fly if I ignored the existing route.
Tomtom 6's slight jerkiness on the TX (which I am told is a feature of the refresh rate) seems to be helped although it seems to takes on a more smooth, smooth, smooth, jump pattern which is interesting.

Any thoughts, comments, advice will be much appreciated...
