我有一个模块，其功能是使用库上的HPRESTCmdlets模块收集HP服务器上的固件版本。该函数为对象分配一个类型名称'Hardware.Firmware'。我正在使用ps1xml进行自定义查看。自定义类型名称慢速输出
该功能由Begin，Process和End脚本块组成。当针对一组对象运行该功能时（通过foreach），第一个对象始终在输出到控制台时被延迟，实际上在End块运行后显示。每个顺序对象按预期运行。如果针对单个对象运行，我也会收到相同的延迟。
如果我删除自定义类型名称，则第一个对象没有延迟并且处理正确。关于为什么在使用自定义类型时处理第一个对象时出现延迟以及如何避免它的任何想法？
这里是该功能的代码：
function Get-HPFirmware {
[CmdletBinding()]
Param(
[Parameter(Mandatory = $true, Position = 0)]
[Alias('Name', 'Server', 'Ip')]
[string]$iLoName,

[Alias('User')]
[System.Management.Automation.PSCredential][System.Management.Automation.Credential()]
$Credential,
[switch]$IgnoreCertFailures

在格式文件中设置显式列宽。或者不要将表格格式用作类型的默认格式。 – PetSerAl
添加宽度有帮助，但为什么？根据msdn宽度是可选的。 – jrob24
因为没有它，格式表必须评估每列的宽度。这通常意味着在收到任何输出之前，您必须等待所有*处理完成。您也可以在使用该功能之前取出导入模块并执行该操作，这也会导致延迟。 – brendan62269
