Scilab 5.0.2 运行缓慢
关于这个问题的解决，只能归功于我的直觉。 记得很久以前听说matlab的Linux版本是java写的，但是跑起来会问题。 我自己试了，确实如此。 但是当时加了参数-nojvm就没有问题，只是失去了java提供的那个图形界面。
于是着手看scilab的问题。
Locale的warning
首先是strace它会发现一个GTK_Warning,大意是说当前的Locale设置得不支持C Library之类，其实后来发现是可以ingnore掉的，不过这个时候我使用
dpkg-reconfigure locales
改变了locale的设置。 因为在另外一台机子上跑没有这个warning，我就设置它为EN_US，这样就和原来的机子一样，代替了原来收到warning的EN_US.utf8。但是这个是有后效性的，它的确影响到了Scim.
罪魁祸首java
改变了locale仍然是缓慢无比。 CPU占用也居高不下。 难道是java的问题？？ 执行
java -version
- 查看java版本。好么...竟然是1.5的。 明明装了sun-java-6的呀。 于是赶紧修改 /etc/profile,添加：
# Java Settings export CLASSPATH=.:/usr/lib/jvm/java-6-sun-1.6.0.07/jre/lib/rt.jar export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.07/ export PATH=/usr/lib/jvm/java-6-sun-1.6.0.07/jre/bin/:$PATH
- 但是还没有结束。 检查Scilab的启动脚本1发现，里面仍然有更新java环境变量的语句，而且是弄到它自带的....郁闷，赶紧换掉。就参照上面的格式。
经过检验，上面的两个地方都得改才能收到效果。
Scim无法呼出
网络上的各种方法试了没有解决。 想到刚才改scilab的时候改了locale。 把locale改回来，带utf8的，就一切正常了。
