II6 Simultaneous ftp file uploads RRS feed

  • Question

  • User-1841015041 posted
    HI Here is the scenario: I have multiple ftp virtual directories, running in IIS6 Windows 2003 server. Each directory is configured for jpeg file uploads to it, at frequency of 1 image per second (20K size each image). (to be exact these are Network Cameras uploading jpeg recording snap shots every second) Now if i have only two to three cameras simultaneously uploading images to their respective virtual directory, there isn't any problem but when the number increases to as many as ten simultaneous cameras, a delay of 5-6 seconds starts appearing between file uploads. Whats puzzling is that LAN is Gigabit, that shows only 0.16% utilization, processor is also only at 1-2% and there is nothing significant in memory consumption as well. Then why is there so much of delay when simultaneous clients increase? where the delay could be coming from and how to optimize that? Any Ideas?

    several factors may affect:

    max user port, the default is 5000 for w2k3.

    disk perfomrnace

    max connections setting is too small, default is 2^32.

    Thanks for your post max connections is already set to "unlimited" and max user port is not required because clients are connected via active mode. however disk performance does seems to be the problem, as i saw from performance monitor, the disk I/O utilization was 100% thanks again
