    hi!

    I have a host with CentOS and CPanel (I guess, the latest versions).

    The download speed via HTTP is about 600KBps. When I uploaded the first file of 15 MB using http POST method (the simple web form is handled by php script) I've got the same speed of 600 KBps. However, when I upload second, third and other files (they are all 10-40 MB of size), the upload speed drops to 70-90 KBps. My connection is quite fast and not loaded, I can download files from my host at the same speed, while uploading become very slow.

    Any ideas, why it happened? Can it be some smart firewall, that automatically limits the upload speed?
    How can I avoid this slowdown? Any Apache tune or may be PHP?

    thanks!

    Hello,

    Please ensure that latest apache version is installed on your server. If not then please ask your host to update the apache version and for better performance and find tuning of apache please go through the following URL,

    "http://httpd.apache.org/docs/2.2/misc/perf-tuning.html"
