snake Posted August 13, 2015 Share Posted August 13, 2015 Ever since we first started using WHMCS years ago we have had random performance issues, every so often pages will hang and take a very long time to load. Often simply refreshing or clicking a link again will make it load, but this is obviously not a viable solution when you are performing an admin function which would cause it to happen twice. Plus on the client side clients do not know to do this. WHMCS is often extremely painful to use when it is going slow. I have done several WHMCS installs, and all of them have had the same issue, on completely different servers. There is no connection problems between the web and db server The MySQL server is performing fine in general and is not showing any bottlenecks. This is running on Windows Server 2012 R2 / IIS (no I cannot switch to Linux as I do not know Linux) I have tried asking WHMCS support but sadly they do not understand how servers work, and have no idea how to troubleshoot php performance problems in general let alone their own app, and simply can't/won't help. Anyone got any suggestions on how to find the problem. Is there some PHP code I can insert to track the processing of the page to find out where the problem is occuring? 0 Quote Link to comment Share on other sites More sharing options...
lee-wservices Posted August 13, 2015 Share Posted August 13, 2015 yes i have noticed the same main site is fine whmcs lags since update and had a couple customers complain they got stuck i have been unable to find any reason why as its same on multiple servers so its not that its the hosting at fault. 0 Quote Link to comment Share on other sites More sharing options...
Serenade Posted February 23, 2016 Share Posted February 23, 2016 So where's WHMCS support on this issue? I'm having major performance issues with my WHMCS install as well, and support has been completely useless. 0 Quote Link to comment Share on other sites More sharing options...
snake Posted February 23, 2016 Author Share Posted February 23, 2016 Sadly I never got any support on this, despite opening numerous tickets. There is little point in asking them about such things frankly as their support guys don't know anything about servers or PHP or MySQL etc and the devs are just typical devs and know how to write php code and upload it to the server, and everything that happens beyond that is just a magical black box. All I ever got from there was "ask your host", which is an absolutely ridiculous response considering we are the host, as are most people who use WHMCS. I did resolve it myself, but I cannot tell you how after all this time, I think I tweaked just about everything and finally somehting worked. MySQL settings PHP settings checked the network performance for bottlenecks updated to newer PHP version upgraded to Windows server 2012 R2 0 Quote Link to comment Share on other sites More sharing options...
