Hello Dears,
I have an issue on Kentico performance

I use the free edition of Kentico versions 5.0 & 4.1, I had hosted them in a shared hosting server, the performance was so bad, so I decided to transfer the hosting onto VPS hosting, it became better, but still I have uncomfortable performance.

to overcome it I have used the caching features based on your recommendations

but still I have something uncomfortable...this happens if I left the websites for minutes without exploring it.

normally the website is loaded within 2-4 seconds, but when I left it for a while it takes about 40+- seconds...

I want to hear from you if you have ideas/suggestions for me that may help

if you need more details, please tell me

try these sites:

http://english.arabchildprotection.com/ (v5.0)
http://haifaag.com/ (v4.1)

Thanks and Regards,
Omar Al-Daher
