I'm not saying that Qt Web Engine would be a problem. I was arguing against "memory is not a problem on developer machines". We still need to be careful of how much we use. Anyway, +150MB for Qt Creator is close to a 20% increase in how much it's consuming right now, with no C++ files open. I'm also seeing 1.2 GB swapped out... > > [*] KMail already starts a QtWebEngineProcess, but the main process is > > right now consuming 950 MB of heap. > > The complain to the KMail developers :) Indeed. Anyway, closing and restarting both applications, KMail dropped to a mere 310 MB heap (530 MB RSS) and Qt Creator increased to 980 MB RSS (but no swap). -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
