I’ve to collect certain events for sharing it by mail; I’m missing something because the script, take a lot of time for only 2 servers and, the result is absurd!

Server1 events count:

    $Etype = @( "Warning", "Error" )
    $Source = "Cisco Systems Inc. ICM"
    $StartDate = ((Get-Date).AddDays(-2))
    $EndDate = Get-Date
    (Get-EventLog -LogName Application -After $StartDate -Before $EndDate -EntryType $Etype -Source $Source).Count
}
$rEVT
2576

Server2 events count:

$rEVT2 = Invoke-Command -ComputerName $Srv2 -scriptblock {
    $Etype = @( "Warning", "Error" )
    $Source = "Cisco Systems Inc. ICM"
    $StartDate = ((Get-Date).AddDays(-2)) 
    $EndDate = Get-Date
    (Get-EventLog -LogName Application -After $StartDate -Before $EndDate -EntryType $Etype -Source $Source).Count
}
$rEVT2
3853

My script:

$HostsTable = @()
foreach ( $Srv in $MyList ) {
$rEVT_ALL = Invoke-Command -ComputerName $Srv -scriptblock {
    $Etype = @( "Warning", "Error" )
    $Source = "Cisco Systems Inc. ICM"
    $StartDate = ((Get-Date).AddDays(-2)) 
    $EndDate = Get-Date
    Get-EventLog -LogName Application -After $StartDate -Before $EndDate -EntryType $Etype -Source $Source | Select-Object -Property TimeGenerated, EntryType, Category, Message
    }| ForEach-Object { 
        [PSCustomObject]@{
            HN = $Srv
            TimeCreated = [DateTime]$_.TimeGenerated
            Category = $_.Category
            Level = $_.EntryType
            Message = $_.Message
        }
        $HostsTable +=  $rEVT_ALL
    }
}

Mesaure command:

(Get-History)[-1].EndExecutionTime - (Get-History)[-1].StartExecutionTime


Days              : 0
Hours             : 0
Minutes           : 18    <--------
Seconds           : 35
Milliseconds      : 898
Ticks             : 11158982764
TotalDays         : 0,0129154893101852
TotalHours        : 0,309971743444444
TotalMinutes      : 18,5983046066667
TotalSeconds      : 1115,8982764
TotalMilliseconds : 1115898,2764

Result:

$HostsTable.count
10011624      <------ :D

Please, help me!
