Very slow upload speed

[ralphbu]

Hello,

I'm struggling with very slow upload times over both HTTP and FTP.

With FTP, I'm getting about 80Kbps with HTTP about 100Kbps. Both going to an IIS server with loads of bandwidth.

When doing the a test using the same machine from the DOS FTP command line, i get about 350Kbps.

If I use the telerik upload control (which i'm trying to replace) for HTTP, I get about 310Kbps.

i have tried doubling the buffersize, but it is just slow. Any suggestions?

Thanks,

Ralph

Which JRE version are you using ?

[ralphbu]

Version 6 Update 16 (build 1.6.0_16-b01)

i tested it on a MACBOOK and it ran at 280Kbps

on my intel i7 development machine it only ran at 78Kbps

both machines were on the same network.

JFileUpload 2.5 + JRE 1.6.0_16/MACOSX = 280 kbps
JFileUpload 2.5 + JRE 1.6.0_16/Windows = 78 kbps
Correct ?

Do you have any firewall or antivirus enabled on Windows ?

[ralphbu]

Windows firewall... default configuration...
no antivirus.

also tried with other windows machines which were also slow.

FTP with filezilla or DOS is fast, so i doubt it is a firewall issue.
