Looking to speed up L4?

I'm running L4 on a Table PC and performance was really poor. The latest version fixed the Table PC problem and the system became usable, but still below expectations.

Good news! I just discovered something that really boosted things, via a disaster. This weekend my harddrive went totally bad - completely caputz. Not a decay - it was gone.

My disk system was:

160gig drive
7,200 RPM
unknown disk Cache size
regular speed 2gig flash memory for ReadyBoost (a Vista feature)

Now I have (Everything else identical):

320 gig drive
7,200 RPM
16 Meg disk cache
high speed 8gig flash memory for ReadyBoost

There is a notable improvement in speed - even with follow features like "Power Lookup" and "Cited By". I think the key is using a harddrive with a large cache. L4 writes to PreferencesManager.db and history.db like there's no tomorrow.

The new hard drive was $125 over at best buy and the flash memory was about $40. The system still jerks on scrolling and I still can't type in the Notes box, but for me the money was worth the boost.

[BTW: Of all the things I had to restore, Logos 4 was the easiest. I downloaded the install program, logged in, and the Logos restored everything I had! Notes, prayer lists, reading plans, the works ... it was wonderful.!)

Can you quantfy that " ReadyBoost " is helping with preformance or could it be the disk cache?

I also wonder the writting to "PreferencesManager.db and history.db" could be my problem in that the AV/Firewall software are hindering/slowing the writting?

I'm going to give ReadyBoost a shot.

If the cache is the reason for the performance increase, then that would mean having L4 on an SSD should be really quick.

Hey Anthony,

I tried before with ReadyBoost on and off. I didn't notice a difference with the old card. Right now, I kinda swamped so I can't run a comparison with the new card. If you are running a laptop (Or have some other UPS system) you can set your harddrive for write-caching. It might help:

Yeah, that's what I was thinking. I was going to try it, but they run about $500+ for a good one. I couldn't justify it. I did have to buy a harddrive, so the $40 for a highspeed flash card was worth the try.

high speed 8gig flash memory for ReadyBoost

High speed is the key for using ReadyBoost successfully. Flash memory can be fast or slow. Unfortunately, most USB flash-drives don't give actual speeds (USB 2.0 doesn't really tell you anything). I've had to dig for performance reviews when purchasing flash memory suitable for ReadyBoost.

Kevin,

Yup, my previous flash card was just fast enough to qualify, this one is better. Also, my laptop has a flashcard slot - it isn't a usb drive. I don't know if that's better or not. The card I paid for was a Class 4 - they are about double the price of a normal one.

Here's another note: you can enable write-caching for the flash drive too.

Here's another, another note: Logos 4 uses your Temp directory for something. I moved my Temp directory to the flash drive too - that helps minimize disk access. You have to be willing to change your environment variables, but if you are bold I can explain that.

THANKS!!

I did some checking with a USB 2 flash stick and there is a plus to the performance. I'll check out write-caching.

I appreciate this insight. [:D]

Anthony,

I now have:

A 7,200rpm HDD with 16 meg cache
A class 4 8gig flash card with 4 gig devoted to ReadyBoost
Write Caching and Advanced Performance set for both the HDD and the flash card.
I moved the Logos Temp directory to the flash card.
I turned on the Windows Font Cache service.

Oh Baby! It's running great.
