Isn't Eclipse horribly slow ? How much time does it take to launch it
for example ?
Hmmm... Isn't this question similarly nonsensical as the one to find out whether it's possible to write an REPL in less than 70 lines just in order to know whether a language is good or not?
Yes, eclipse is slower than most native compiled apps, but where does the startup time come in? I don't really think it costs my company that much for me to wait another 10 seconds (if that much) to start eclipse; I think they are more interested in whether I can work productively with it, or whether it will cost me more time due to bad user interface design or other issues.
The startup cost only comes into the equation once or twice a day at most (if I use it on the laptop I carry between work and home), or maybe once a month (if it's on the desktop machine at home/work, i.e. about once per login cycle); if that much...
There are things in eclipse worth noting as "not very sophisticated", but I wouldn't waste time comparing startup times for IDEs as a measure of quality.
