Help using different libs: rdflibjs, tripledoc, ldflex, solid-file-client

Hi Soliders are there big performance differences between the different libs

I’m asking that because I must impove performance of Shighl for Solidarity’s Chat.
For now Shighl is based on query-ldflex, but i think there is a lot of await to parse all chat messages and @jucole confirm some degradation So does anyone have an idea of which is the most performant for this task before i start to rewrite ?
Or do I have to low deal with Sparql query ?
