Indexing Is Considerably Faster With Quad Cor Processor

When I first loaded Beta 1 on my desktop, my time for indexing was almost 30 hours (Loud Groan). At that time I had a DuoCore 2.4 processor and 2 gig of memory. That first week I upgraded my memory to 8 gig and saw some improvement in my indexing time. I had removed the Beta 1 from my laptop because I couldn't have it bogged down, as I needed it for work.

This week I upgraded my desktop processor to a Q9650 3Gz processor and was amazed at how much faster the indexing was. I currently have in Logos 4, 7564 resources listed in the Library. I went from 9 hours and 40 min with my DuoCore to 6 hours and 32 min with my QuadCore, that's 3 hours shaved off of the indexing time!

I then reloaded Beta 5 on my laptop which orginally got about the same time for indexing as my destop, It has a 2.5 Gz DuoCore with 4 gig of memory. The total time for indexing the identical library is 9 hours and 55 min.

It seems as though the indexing really takes advantage of the QuadCore to shorten the indexing time.

I am certainly not a computer specialist but I noticed that my L4 directory is now over 9GB in size. I would be willing to bet that taking the time to make a few passes with a hard disk defragmenter would help speed things up, too, for anyone who doesn't normally do it.

Heck, it was only using 3 cores (33% improvement instead of 50%)[:)]

About 80% of the time of indexing is spent in work that can be easily parallelised; the other 20% (approximately) is basically single-threaded. So, upgrading from a single-core to a dual-core machine gives you about 1.6x speed-up, and going to quad-core gives a 2.5x speed-up over single core and 1.5x speed-up over dual-core.

Changing CPU architecture (e.g., Pentium 4 to Core 2 to Core i7) or clock speed will also give a (sometimes dramatic) speed increase. (A Core i7 at 2.4GHz is probably an order of magnitude faster than a P4 at the same clock speed.)
