after that and then the connect times out after a total of around seconds.On Linux However, the default retry cycle ends after just seconds. Linux does send SYN retries somewhat faster than bsd-derived Kernels-linux supposedly sends 5 SYNs in this seconds, b UT this includes the original packet (the retries is after 3s, 6s, 12s, 24s).The end result though is so if your application wants a connect timeout shorter than 20s, no problem, but if your appl

than a single insert, but the size of one batch has little effect on performance. The parameters of whether each record refreshes the log have a significant impact on InnoDB performance. Overall, MyISAM performance is a bit more superior. One thing to note here is that during the insertion test, I monitored the system resources and found that MyISAM is very low on system resources, but InnoDB is very high on disk, and should be a lot more logs to log for transaction control.Test two: Data read
