As a multitasking operating system OS/2 was quite a bit better then Windows 95. If IBM could have marketed it there would have been drivers and popular applications. They couldn't get hardware manufactures to write drivers and software developers to write software. That's what killed OS/2. I don't know if it took longer to boot then Windows. My gauge was it didn't crash. I ran a 4 line BBS with an uptime of over 200 days until I had a power failure.
