performance

Hi Long story short, we have to run an ec2-instance to serve 5K connections per second. We tried to take bigger and bigger instances but for some reason the vmstat always showing the machine peaking the kernel-time with the CPU cores being at 100% usage. We are testing with a php script that...

Running 2 sites on 2 separate accounts on my server. For the past 48 hours, performance has been woeful. On both sites. Checked all the usual things - everything seems normal. Server load is actually lower than usual (I expect because people can't get on the sites). Pages on the sites...

Hi, My cpanel server specs are : I will appreciate some suggestions to optimize my server to handle wordpress sites with more than 5000 people online at peak. My server used to handle 3000 people online at a time with no problems, but for last couple of days my traffic has doubled and it is...

Hello, I wonder what is the suggested approach an why? When I am on a reseller account myself, should I create better a separate account for the live site and the dev environment? Or is it better to just have them in one account? I wonder if the performance would be impacted in a different way...

Hi team, I am trying to increase the performance of a Cpanel account, as it is not performing well. It has a high resource consumption because it is a heavy and powerful web, but I can't manage to enable more resources for it. Among the options I can see that there is an option to limit the...

Hello, I'll need to host between 200 to 300 hosting accounts, most of them WordPress installations and and average of 20 email accounts each. Server should run DNS, mariadb, php7, exim, dovecot, spamd, etc. What would be the recommended hardware for that kind of load? Thank you in advance for...

My web/email server is going down several times a day because of the process [jbd2/md1-8] which is using 99.99% IO according to iotop. I've realized that MySQL (MariaDB 10.3.28) has something to do with it: the problem seems to be caused on database reading/writing. I benchmarked the HD and...

Hello, When I try to connect through ssh and became a specific user I get this bash error. I read this thread and tried the solution presented by ispro but when I run the script I get this errors: 1 out of 1 hunk FAILED -- saving rejects to file bashrc.rej 1 out of 1 hunk FAILED -- saving...

I am in the process of slowly setting up a replacement cPanel/WHM server to move all of hosting to from a server that was compromised last month. Every time i get close to prime time for the full migration another test seems to fail. This time we deployed a brand new WordPress site to the new...

I'm setting up a new VPS, and I'm strongly considering turning off mod_security2 and mod_unique_id. I understand that there's a significant performance hit from them, and I don't use mod_unique_id in any of my written applications. When I turned it off, though, it took mod_security2 with it...

I'll try to keep this short and clear. Sorry if I failed. ;) I can not get caching working on one of my cPanel accounts and it's domains. I have multiple domains under one account, when I do a fresh Wordpress install, by default gives this response header: cache control: private...

Hello, I have an idea and I wanted to know your opinion, if someone hires for example a reseller account in a hosting, where each cpanel account has limited resources (ram, cpu, i / o, etc), they could use a cpanel account only for database data and another cpanel account to have my site...

Good morning, In order to debug slow websites, I need PHP slow log. With PHP-FPM, I used to enable PHP-FPM slow log (like this). I'm looking for similar feature on LSAPI, but I didn't found any yet. Is there any documentation about it for cPanel? Thanks in advance.

Recently I have noticed that transferring files to a certain account on my server via SFTP is extremely slow. I have tested on other accounts including root on the same server and it is fine. FTP is fine for all users. Instead of using all 10 threads, only 1 file gets uploaded per approximately...

Will the cPanel installation on VPS perform the same, worse or better than the cPanel Dedicated server? Hypothetically, the dedicated server specs would be similar (if not exact) to the KVM VPS specs. 16 gigs of ram Intel Xeon E5-2620 v2 @ 2.10GHz 80G SSD CloudLinux Just curious, maybe you've...

Hi all, Looking for some guidance please; We have a WHM VPS we have finished migrating our accounts to - 49 in total. Everything is running nice and smooth and the migration process was largely straight forward (kudos to the Transfer Tool). Currently the server is processing ~1000 a day...
