Hey @Chenkai, thanks for the question. > Is the performance related to server memory size or is there any configuration? Yes, there is a configuration file. > Is there a limit on the size of documents loaded by Collaborator Online? No. Not limits in memory, but it does limit load time. Back [in 2021, mmeeks described how to tweak](https://forum.collaboraonline.com/t/error-loading-140mb-xlsx-file/398/2): - `coolwsd.xml` = the main Collabra Online settings file - + `limit_load_secs` = the “don’t let a document load for longer than X seconds” setting In the XML file, it describes: > “Maximum number of seconds to wait for a document load to succeed. 0 for unlimited.” so if you change it to `0`, that would let Collabora take as long as it needs to load some behemoth-sized document. By default though, these limits are in place so one runaway user/document can’t suck up all the resources and jam up everyone else. If you’re the only one using it, or if you’re going to only have a handful of trustworthy users using Collabora, then sure, make it unlimited. 🙂 --- _[View the full topic](https://forum.collaboraonline.com/t/is-there-a-limit-on-the-size-of-documents-loaded-by-collaborator-online/1760)._
