Intel超线程技术导致服务器性能降低？

Intel曾经声称一旦多线程软件问世，其处理器超线程（HT）技术的优势就能体现出来，但是看起来实际情况却是恰恰相反。超线程技术降低服务器性能的弊病已经备受指责。有报道指出，在高负荷情况下，启用HT将导致SQL和Citrix Terminal服务器的性能显著下降，关闭HT则恢复正常水平。

英国财务软件公司Lakeview Computers的技术总监Peter Ibbotson说：“我们的客户一直在抱怨当在一台机器上同时运行Citrix Terminal Server和我们的软件就会导致性能低于预期的问题。过去当我们启用HT之后感觉不错，而许多主板也默认启用HT，但现在当我们一禁用HT，性能立即就恢复了正常。”
