Long waiting time before transfering data to browser
By ghumanz
Hi please take a look on this, I notice that my site's waiting for response time is very long above 2 sec. with single php.info file or any other small pic .
Rest of all processes take only ms to respond .
I am on VPS with 1.5 GB RAM, 2.27 GHZ CPU and 100 Mbps netspeed. In below snapshot no dns and no connectivity issue is looking. only waiting time is long which hurts.
I am using e-accelerator, mem cache, query cache for MySQL. Simple cache on. I test this on my local LAMP server and found same results which shows that no problem with server.
On peak time 50-70% of CPU use and 40-50% of Ram usea So it is look alike no issue with Server stats.
Please advise me how to fix this issue , I think if we resolve this it helps all of elgg users.

You must log in to post replies.Here is a snap shot:-
Here are some more testing results:-
Your Time To First Byte is: 2.395 seconds
Extended Information:
This is *not an issue with Elgg at all ;-)
You speeds looks pretty good from here...
If you subtract the first byte time from total time;
= 0.286 secs !!
You'll not get that on a VPS yet ;-P
What part of that "hurts" ??
And what on earth could be open to "fixing" ?
I'd say if you want better performance than what you got already...
Should search Seasoned Linux/Apache Perf Consultant;
Linux/Apache monitoring & tuning can and will take
hours and hours of time over several weeks ;-oO;X;P
Cheers.
Hi Dhrup Thanks for your advice I will definately hire some database administrator but this is not a right time for that.
Ok I did some changes to apache, mysql and instead of mem-cache, now using disk-cache. these changes done a trick and check results below:-
One more thing I want to ask core members I found this post related to this problem:- Is that issue with simple cache was resolved or still having same problems?
