I have been trying out MEGA using Ubuntu 12.04, it really expects Chrome browser, so I have been using the repository Chromium and also Google Chrome. In many ways it works surprisingly well. However, the test I was mostly using was upload of a folder containing a total of approximately 650 small-ish files. In several tests over a couple of days now, I found that the browser crashed after some time. Inconveneint because the upload set then is not recoverable, and it seems not possible to collate, compare, whatever, the then partial upload.
I then tried first compressing the files into a single archive file, and this uploaded fast without problem (65MB or so).
I conclude so far that, for me, whatever is happening in the browser for multiple files, is not yet stable.
Anyone any experiences?
Edit: Just tried again, it crashed after approximately 150 files uploaded. The (Edit) memory used had increased from initial 20% to 50% (of 4GB) FWIW.
