Optimising Intella (Slow performance)

Hi

 

Have been getting inconsistant results where performance is very slow and where it runs at about 1000 items a minute for a short burst then for hours at 1-10 items a minute.

 

It doesn't seem to be a hardware issue as it's not using much RAM and not utilising the CPU very much. The HDD is a SSD which isn't highly utilised.

 

System is a core i7 CPU with 8GB RAM and the case & evidence on a 250GB SSD.

Evidence is 3 PST files with a total size of 38GB.

 

I have tested against an alternative product which also uses lucene and it's a lot faster. (~4x faster)

Have attached an image showing the dropoff in performance.

 

 

Any recommendations for optimising it ? Would prefer to use Intella.

 

Regards

Daniel

Hi Daniel,

 

Strange indeed. I would expect no more than 3 hours for that case. The slow indexing speed point to a problem somewhere. 

 

Would you have the time to try the following:

 

1. Try the case on 2 drives. One for the case file and one for the evidence.

2. Try the case on a non SSD drive - I know this sound silly but worth ruling out. 

3. Send us the logs

 

Can I ask if you are using the 64 bit version or the 32 bit?

Are you using 1.7.1?
