    Email server, where is the bottleneck?

    No, just a few thousands < 10k per mailbox, averages 2k maybe. Yep, I'm now considering that it's more of an I/O issue rather than CPU or memory, will figure out which provider is best for me.

    Email server, where is the bottleneck?

    I've checked my stats and my disks are the culprit for this, util is around 60-90 that's why I can't compare it on my end. It's also a cPanel server, performance is mixed. CPU utilization is actually on the low part why memory is more on MySQL.

    Email server, where is the bottleneck?

    A pretty old L5520 :) Yep, I pretty much guessed that VPS would suffice. But I still don't know which resource IMAP and Roundcube use the most, is it CPU or memory? And where it would benefit more. I can't base it on my usage as my disks are pretty slow (and old) :(

    Email server, where is the bottleneck?

    My current server is actually sending about 10k emails a month, valid transactional and regular emails. Active domain senders are around 10 with less than 10 active accounts each. I dont mind deliverability as I'm using mailchannels. Though I currently have local anti-spam processes and...

    Email server, where is the bottleneck?

    If I'm to put up a server dedicated for emails (currently being used for IMAP and Roundcube), which bottleneck should I focus on? Is it CPU or memory? I'm thinking of getting a VPS first (both companies I'm checking out have SSDs, so I don't think I/O should be an issue). They just differ with...

    KVM guest with higher CPU than host

    Fixed this!  Never set vCPUs with # of HTs, just physical cores :) I/O increased from 80-100mb to 130+ And 1mb for sort/read/join buffer on MariaDB seems to be the magic number.

    KVM guest with higher CPU than host

    This seems to be a case of MySQL filling up cache and might be KVM over committing CPU. Most of my MySQL queries are for reading consuming at least 80% of total queries, right now, it's now in 20% of my 16gb RAM (no swap) and server has been stable for at least 48 hours. Previous months...

    WHM 54.0 updates

    That update broke down my /mailhelo and /mailips due to IPv6 compatibility. Got massive blacklisting because of this and cPanel support blamed scripts, had to find this the hard way. Fixed at Build 15.

    KVM guest with higher CPU than host

    During recent normal usage with load average ranging from (0-2), there's just quick spikes from ext4 journal (with noatime in fstab) reaching up to 99% - from mysql/lsphp processes. This recent cPanel update (forced), journal seems to be fine (peaking at around 25% quick spike) and disk load...

    KVM guest with higher CPU than host

    Is it normal for KVM guest to have higher CPU usage when host is pretty much idle? I have this dedi server, only 1 cPanel server in it, using 8 vcpus (no other tuning in virsh xml) I did a force upcp update where it hogged a lot of resources, 80-95%~ wait time for about 5-10 minutes...

    Who was your first VPS provider?

    I was late to the party, I think Slicehost was already purchased that time when VPSs piqued my interest. First one.. VPSLatch I think, now owned by Hostdime :)

    Oracle tells its customers to stop analyzing its code

    Oh wow, I wonder what will replace Java in the enterprise market in the near future..  Depending on seals alone and distrusting security analysts, oh just wow, I can't imagine the chaos. I worry for her future.

    Mariadb tokudb foreign keys

    Quick question, since tokudb does not enforce foreign key constraints, does that mean cascade deletes won't work? I'm kinda confused on this, sorry --- EDIT: oh yeah, found my answer. tokudb don't have foreign keys and i'm developing on an innodb :(

    FYI: Planned vpsBoard maintenance will be occuring later this evening.

    I'm not backtracking so forgive me if this has been posted earlier.. the header ad's length is ruining the responsive design in mobiles -- specifically, it hides the navigation until you zoom out and look for it.
