Why is OpenLCA so slow?

Question

Hello everyone!

OpenLCA is very slow on my computer. Whether it's for calculations or even just opening the inputs and outputs of a LCI, it's incredibly slow.

The software doesn't crash completely. It often displays "Not responding" for one or a few minutes before finally displaying the requested data or result.

My PC should have sufficient storage and RAM.

I'm using EcoInvent 3.11.

My current software version is 2.6, but this problem was also present in versions 2.4 and 2.5.

Could someone help me identify the cause of this problem?

Thank you in advance.

So what do you do? How much RAM did you give to openLCA? How is it installed (on a remote disc?)? Which databases are you using? On a recent computer, openLCA should calculate ecoinvent 3.11 in less than a minute, and using the libraries within a few seconds.

Comments

Hello,

Same here, I see a lot of IO while RAM and CPU are not under any stress. It seems that disk access is causing freezes in OpenLCA 2.6 using EI3.12.

I would really appreciate any suggestions as its blocking me from using OpenLCA atm.
