Export to Excel with jXLS can be faster


I got a question about the jXLS performance, in short it was like “jXLS is a kind of slow for my big reports”.
I mentioned that in my previous post (Creating Excel reports from java is easy)

It’s true, especially about latest jXLS, after I updated my jxls-0.9.8 to 1.0-RC1 (see downloads) I noticed that report generation become MUCH SLOWER. I believe the difference is in the expression library version JEXL. In the 1.0-RC1 they start using JEXL-2.0.1 version and before they use JEXL-1.1
Anyway, it looks downgrading it back to the jXLS 0.9.8 solves my problems, the performance is not blazing fast but much better than in jXLS 1.0. I bet jXLS 0.9.9 work faster than 1.0
