Crossjoin Clients and Success Stories

We were having sporadic performance issues and we were struggling to understand the cause.
In a very short period, Crossjoin identified the root cause and proposed a simple but very effective correction plan.
Since then, we trust Crossjoin to help us on complex infrastructure related issues and we are very happy with this partnership.

I strongly recommend Crossjoin as a company specialized in performance issues. In our area, they managed to increase the performance of the GLX/JSP flow from more than 24 hours (best time obtained by our off shore delivery team) to only 1,30 hour!!
