Vector graphics load slowly

[15797622650]

Hello, i'm evaluating Spire Pdf Viewer,when loading the drawing pdf, the loading is very slow.
All the drawings used are vector diagrams, about 20M in size.
Is it the poor support for vector diagrams, or is it the problem I use
private void frmMain_Load(object sender, EventArgs e)
{
string base64 = DataProvider.GetBase64Stream(119131);
var ms = new MemoryStream(Convert.FromBase64String(base64));
pdfDocumentViewer1.LoadFromStream(ms);
}
Versions are:Spire.PDFViewer .NET 7.12.0
