In a perfect illustration of Murphy’s law, the big upgrade we did to our grid introduced some performance issues in Zoho Writer. The very reason to move to the grid architecture was to provide higher scalability and performance, and have more redundancy. We now provide a search feature for documents as well, something pending for a while. Alas, we also seem to have introduced some new bottlenecks in the code.
We apologize for the inconvenience. We hate low performance in web apps ourselves, and this is the highest priority item for us. Rest assured we are working hard on it. We will update as soon as we have some news.
