SQLITE with Roundcube performance

I'm experiencing some slowness with roundcube site when the concurrency ramps up..

How can verify it's sqlite the bottleneck ?

By php-fpm i found the slowest requests are related when use the db (sqlite)

I choosed sqlite in place of mysql becaouse at least this web email site it not very hgith traffic site .

I think we can get maximum 20 request per second and i deployed on a single linux vm on azure on the same disk SSD very fast.

Looking at vmstat 1 100 i dont see any block ...
