Hello,

It is definitely recommended in 3 cases.

1) You are using the newest MySQL/MariaDB version.

or
2) You are experiencing the loss of productivity due to the Meltdown Fix.

or
3) You are experiencing the MySQL error 'MySQL table is marked as crashed and should be repaired'
https://confluence.atlassian.com/confkb/mysql-table-is-marked-as-crashed-and-should-be-repaired-151519802.html

In other cases, it is recommended to measure the BEFORE/AFTER performance on a dev server.

Thank you.

Re: X-Cart 4.7.10 released

For the past few days we're experiencing periodical site outages. Host support staff claim the reason most probably was very high bot activity with bots hitting the site and tying up MySQL queries.
As one of the measures they suggest switching from MyISAM to InnoDB.

Are there any changes in 4.7.10 as compared to 4.7.9 that would cause issues if x-cart is subjected to high bot activity?

Could you ask your hosting for the bot's HTTP_USER_AGENT?
Maybe our XCRobots::getRobotsSignatures() method has to be corrected.
It should help to reduce the amount of MySQL queries.

Thank you.

Re: X-Cart 4.7.10 released

I'v been having sql errors ever since this update. Today i was locked out of admin after a xcart_sessions_data sql error. Repairing the tables fixed it.

Not sure if it matters but its a InnoDB table. Most of my tables are MyISAM. I'm running 10.2.18-MariaDB

It should be noted that I also updated to the latest MariaDB just before the update

Google page speed insight results have in fact improved drastically both for mobile and desktop. Thanks for that!

The most heavily active bots for the past few days were MJ12bot (200K+ hits & 4.8+ gigs), Semrushbot, Baidu, and some others. There are a couple of Unknown bots as well.

Yep, that looks right. Just make sure the table is backed up first.

Here is more info on InnoDB: https://dev.mysql.com/doc/refman/5.5/en/innodb-introduction.html

It will prevent xcart_sessions_data table overload.

Thank you very much for the patch!

We could eventually switch our site to use an InnoDB copy of the database for a while to see what happens. Wonder would it be wise to do it?

Please contact our support staff at https://secure.x-cart.com/ - I'm not sure if this is something that can be solved via a forum discussion, unfortunately.

Thank you.
