I&nbsp;found&nbsp;it`s&nbsp;so&nbsp;slow&nbsp;when&nbsp;i&nbsp;use&nbsp;jcifs&nbsp;to&nbsp;get&nbsp;file&nbsp;from&nbsp;a&nbsp;remote&nbsp;server,&nbsp;only&nbsp;around&nbsp;10mb,&nbsp;<div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div style="font-size: 12pt; font-family: times new roman,new york,times,serif;"><div><div><font size="2" face="Verdana">

<div>but&nbsp;it`s&nbsp;very&nbsp;fast&nbsp;when&nbsp;i&nbsp;use&nbsp;the&nbsp;direct&nbsp;url&nbsp;to&nbsp;get&nbsp;the&nbsp;same&nbsp;file,&nbsp;the&nbsp;speed&nbsp;was&nbsp;up&nbsp;to&nbsp;80mb,&nbsp;</div>

<div>i&nbsp;set&nbsp;the&nbsp;property&nbsp;jcifs.smb.client.rcv_buf_size&nbsp;with&nbsp;value&nbsp;1024*1024,&nbsp;but&nbsp;</div>

<div>it&nbsp;didn`t&nbsp;work,&nbsp;so&nbsp;i&nbsp;noticed&nbsp;the&nbsp;jcifs&nbsp;src&nbsp;code,&nbsp;i&nbsp;found&nbsp;the&nbsp;default&nbsp;constructor&nbsp;of&nbsp;</div>

<div>SmbFileInputStream&nbsp;set&nbsp;readSize&nbsp;to&nbsp;the&nbsp;mini&nbsp;value&nbsp;between&nbsp;</div>

<div>transport.rcv_buf_size&nbsp;and&nbsp;transport.server.maxBufferSize,&nbsp;when&nbsp;i&nbsp;debug&nbsp;it,&nbsp;i&nbsp;found&nbsp;maxBufferSize&nbsp;</div>
