I have online shop based on Zencart 1.3.9. It has run abouth 4.5 years, and has around 20k orders. From 2 days ago, the performance become unstable, in particuarl, sometimes the response time is quite quick, whereas, sometimes it become very slow, even non-responsive. We have asked our hosting company to do a check, here comes their results:
"I carefully investigated your case. In our server logs I noticed a large number of slow queries executed from your account. Coupled with a large number of visitors to your web site this slow queries will cause a slow performance. I advice you to contact a professional developer to optimize your MySQl databases."
So please let us know
