ODS显卡速度极慢(慢800倍)

Question

ODS图形打开选项产生更好的图形，但似乎比基础图形多花800倍的时间。我用各种不同的程序体验过这一点。平台是windows 7上的SAS 9.4。

Q1:这是典型的/预期的吗？我可以发誓，去年在同事的机器上生成ODS图表的速度要快得多。

Q2:我如何才能加快速度，现在我可以手动创建图表，比ODS图形更快。此外，基础图表看起来不够专业，也许有一种方法可以将它们自动导出为具有抗锯齿字体的像样的png或svg格式？(请记住，我想编写一个自动创建数千个图表的程序)。

Q3:我应该放弃ODS图形，转而使用传统图形吗？

下面是一个例子。如果您执行这段代码并查看日志中的执行时间，我看到关闭ODS图形的shewhart过程的执行时间是0.09秒，而打开ODS图形的时间是1:13.11秒甚至1:20.23秒。如果我另外请求html输出，每个图表可能需要2分钟以上的时间。

更新:我认为这与打印机(是物理的)访问有关。

Answer 1

事实证明这与打印机访问有关。

我注意到，在其他桌面应用程序中，有时需要大约20秒才能访问远程默认打印机。

其次，我还注意到，当我在打印机可访问的网络上时，生成每个图表所需的时间要短得多。

然后，我将我的默认打印机切换到了一个人造adobe pdf生成器。这将图表生成时间从1-2分钟缩短到0.09秒。

该效果可通过切换回不可达的网络打印机来再现，并可通过从网络打印机切换而再次解决。

因此，PROC SHEWHART和其他操作似乎被延迟，并在每次要生成图表时等待联系网络打印机，即使图表不会发送到打印机。

Answer 2

我无法复制您的结果，在Linux服务器上运行9.4。

有时ODS图形对我来说确实很慢，但它更像是每个图形慢半秒，而不是10秒或2分钟。我认为@Reeza关于尝试技术支持的建议是很好的。

我在你的更新中看到，你关闭了所有的ODS目的地有帮助。当然，如果你打开了多个目的地，可能需要不同的图像格式，这会减慢速度。但是，对于一个简单的图表来说，2分钟似乎仍然超出了范围。
