solaris IO 正常么？
本系统挂了一个30T的盘阵~
然后由 SOALRIS 分成了两个区~做成ZFS文件系统~做了两个~pool~分别为ZPOOL1 zpool2~
现在系统每秒种向zpool1 写小文件~大约100K一个~一秒可能几百个~
IO情况如下：
写文件的程序大概如下：
for(int i=1 ;i<10000;i++)
{
FILE *f fopen();
fwrite();
fclose(f);
}

IO常常都是 b% 大部分时间都是：100%
是系统没有优化好？还是程序写文件太多太快了？出现IO写文件很不稳定~~~~？

CPU,内存,IO直接的关系。

[解决办法]
io太高了，建议减少写盘次数，增加每次写入的数据量
